 # Build System Changes for Android.mk Writers
 
+## Genrule starts disallowing directory inputs
+
+To better specify the inputs to the build, we are restricting use of directories
+as inputs to genrules.
+
+To fix existing uses, change inputs to specify the inputs and update the command
+accordingly. For example:
+
+```
+genrule: {
+    name: "foo",
+    srcs: ["bar"],
+    cmd: "cp $(location bar)/*.xml $(gendir)",
+    ...
+}
+```
+
+would become
+
+```
+genrule: {
+    name: "foo",
+    srcs: ["bar/*.xml"],
+    cmd: "cp $(in) $(gendir)",
+    ...
+}
+```
+
+`BUILD_BROKEN_INPUT_DIR_MODULES` can be used to allowlist specific directories
+with genrules that have input directories.
+
 ## Dexpreopt starts enforcing `<uses-library>` checks (for Java modules)
 
 In order to construct correct class loader context for dexpreopt, build system

+# `dex_preopt_check`
+
+`dex_preopt_check` is a build-time check to make sure that all system server
+jars are dexpreopted. When the check fails, you will see the following error
+message:
+
+```
+FAILED:
+build/make/core/tasks/dex_preopt_check.mk:13: warning:  Missing compilation artifacts. Dexpreopting is not working for some system server jars
+Offending entries:
+```
+
+Possible causes are:
+
+1.  There is an APEX/SDK mismatch. (E.g., the APEX is built from source while
+    the SDK is built from prebuilt.)
+
+1.  The `systemserverclasspath_fragment` is not added as
+    `systemserverclasspath_fragments` of the corresponding `apex` module, or not
+    added as `exported_systemserverclasspath_fragments` of the corresponding
+    `prebuilt_apex`/`apex_set` module when building from prebuilt.
+
+1.  The expected version of the system server java library is not preferred.
+    (E.g., the `java_import` module has `prefer: false` when building from
+    prebuilt.)
+
+1.  Dexpreopting is disabled for the system server java library. This can be due
+    to various reasons including but not limited to:
+
+    - The java library has `dex_preopt: { enabled: false }` in the Android.bp
+      file.
+
+    - The java library is listed in `DEXPREOPT_DISABLED_MODULES` in a Makefile.
+
+    - The java library is missing `installable: true` in the Android.bp
+      file when building from source.
+
+    - Sanitizer is enabled.
+
+1.  `PRODUCT_SYSTEM_SERVER_JARS`, `PRODUCT_APEX_SYSTEM_SERVER_JARS`,
+    `PRODUCT_STANDALONE_SYSTEM_SERVER_JARS`, or
+    `PRODUCT_APEX_STANDALONE_SYSTEM_SERVER_JARS` has an extra entry that is not
+    needed by the product.

+# Ninja File Canonicalizer
+
+Suppose we have a tool that generates a Ninja file from some other description (think Kati and makefiles), and during
+the testing we discovered a regression. Furthermore, suppose that the generated Ninja file is large (think millions of
+lines). And, the new Ninja file has build statements and rules in a slightly different order. As the tool generates the
+rule names, the real differences in the output of the `diff` command are drowned in noise. Enter Canoninja.
+
+Canoninja renames each Ninja rule to the hash of its contents. After that, we can just sort the build statements, and a
+simple `comm` command immediately reveal the essential difference between the files.
+
+## Example
+
+Consider the following makefile
+
+```makefile
+second :=
+first: foo
+foo:
+	@echo foo
+second: bar
+bar:
+	@echo bar
+```
+
+Depending on Kati version converting it to Ninja file will yield either:
+
+```
+$ cat /tmp/1.ninja
+# Generated by kati 06f2569b2d16628608c000a76e3d495a5a5528cb
+
+pool local_pool
+ depth = 72
+
+build _kati_always_build_: phony
+
+build first: phony foo
+rule rule0
+ description = build $out
+ command = /bin/sh -c "echo foo"
+build foo: rule0
+build second: phony bar
+rule rule1
+ description = build $out
+ command = /bin/sh -c "echo bar"
+build bar: rule1
+
+default first
+```
+
+or
+
+```
+$ cat 2.ninja
+# Generated by kati 371194da71b3e191fea6f2ccceb7b061bd0de310
+
+pool local_pool
+ depth = 72
+
+build _kati_always_build_: phony
+
+build second: phony bar
+rule rule0
+ description = build $out
+ command = /bin/sh -c "echo bar"
+build bar: rule0
+build first: phony foo
+rule rule1
+ description = build $out
+ command = /bin/sh -c "echo foo"
+build foo: rule1
+
+default first
+```
+
+This is a quirk in Kati, see https://github.com/google/kati/issues/238
+
+Trying to find out the difference between the targets even after sorting them isn't too helpful:
+
+```
+diff <(grep '^build' /tmp/1.ninja|sort) <(grep '^build' /tmp/2.ninja | sort)
+1c1
+< build bar: rule1
+---
+> build bar: rule0
+3c3
+< build foo: rule0
+---
+> build foo: rule1
+```
+
+However, running these files through `canoninja` yields
+
+```
+$ canoninja /tmp/1.ninja
+# Generated by kati 06f2569b2d16628608c000a76e3d495a5a5528cb
+
+pool local_pool
+ depth = 72
+
+build _kati_always_build_: phony
+
+build first: phony foo
+rule R2f9981d3c152fc255370dc67028244f7bed72a03
+ description = build $out
+ command = /bin/sh -c "echo foo"
+build foo: R2f9981d3c152fc255370dc67028244f7bed72a03
+build second: phony bar
+rule R62640f3f9095cf2da5b9d9e2a82f746cc710c94c
+ description = build $out
+ command = /bin/sh -c "echo bar"
+build bar: R62640f3f9095cf2da5b9d9e2a82f746cc710c94c
+
+default first
+```
+
+and
+
+```
+~/go/bin/canoninja /tmp/2.ninja
+# Generated by kati 371194da71b3e191fea6f2ccceb7b061bd0de310
+
+pool local_pool
+ depth = 72
+
+build _kati_always_build_: phony
+
+build second: phony bar
+rule R62640f3f9095cf2da5b9d9e2a82f746cc710c94c
+ description = build $out
+ command = /bin/sh -c "echo bar"
+build bar: R62640f3f9095cf2da5b9d9e2a82f746cc710c94c

+build foo: R2f9981d3c152fc255370dc67028244f7bed72a03
+
+default first
+```
+
+and when we extract only build statements and sort them, we see that both Ninja files define the same graph:
+
+```shell
+$ diff <(~/go/bin/canoninja /tmp/1.ninja | grep '^build' | sort) \
+       <(~/go/bin/canoninja /tmp/2.ninja | grep '^build' | sort)
+```
+
+# Todo
+
+* Optionally output only the build statements, optionally sorted
+* Handle continuation lines correctly

+## Test data
+
+Each non-regression directory under testdata/ defines a similar build graph.
+All have the same structure, but different versions of the graph have different
+license metadata.
+
+The regression* directories can have whatever structure is required for the
+specific test case.
+
+### Testdata build graph structure:
+
+The structure is meant to simulate some common scenarios:
+
+*   a `lib/` directory with some libraries
+*   a `bin/` directory with some executables
+*   one of the binaries, `bin3`, is a toolchain executable like a compiler
+*   an `application` built with the `bin3` compiler and linking a couple libraries
+*   a pure aggregation `continer.zip` that merely bundles files together, and
+*   an apex file (more like an apk file) with some binaries and libraries.
+
+The testdata starts with a `firstparty/` version containng only first-party
+licenses, and each subsequent directory introduces more restrictive conditions:
+
+*   `notice/` starts with `firstparty/` adds third-party notice conditions
+*   `reciprocal/` starts with `notice/` and adds some reciprocal conditions
+*   `restricted/` starts with `reciprocal/` and adds some restricted conditions
+*   `proprietary/` starts with `restricted/` and add some privacy conditions

+
+Package compliance provides an approved means for reading, consuming, and
+analyzing license metadata graphs.
+
+Assuming the license metadata and dependencies are fully and accurately
+recorded in the build system, any discrepancy between the official policy for
+open source license compliance and this code is a bug in this code.
+
+A few principal types to understand are LicenseGraph, LicenseCondition, and
+ResolutionSet.
+
+LicenseGraph
+------------
+
+A LicenseGraph is an immutable graph of the targets and dependencies reachable
+from a specific set of root targets. In general, the root targets will be the
+artifacts in a release or distribution. While conceptually immutable, parts of
+the graph may be loaded or evaluated lazily.
+
+LicenseCondition
+----------------
+
+A LicenseCondition is an immutable tuple pairing a condition name with an
+originating target. e.g. Per current policy, a static library licensed under an
+MIT license would pair a "notice" condition with the static library target, and
+a dynamic license licensed under GPL would pair a "restricted" condition with
+the dynamic library target.
+
+ResolutionSet
+-------------
+
+A ResolutionSet is an immutable set of `AttachesTo`, `ActsOn`, `Resolves`
+tuples describing how license conditions apply to targets.
+
+`AttachesTo` is the trigger for acting. Distribution of the target invokes
+the policy.
+
+`ActsOn` is the target to share, give notice for, hide etc.
+
+`Resolves` is the license condition that the action resolves.
+
+Remember: Each license condition pairs a condition name with an originating
+target so each resolution in a ResolutionSet has two targets it applies to and
+one target from which it originates, all of which may be the same target.
+
+For most condition types, `ActsOn` and `Resolves.Origin` will be the same
+target. For example, a notice condition policy means attribution or notice must
+be given for the target where the condition originates. Likewise, a proprietary
+condition policy means the privacy of the target where the condition originates
+must be respected. i.e. The thing acted on is the origin.
+
+Restricted conditions are different. The infectious nature of restricted often
+means sharing code that is not the target where the restricted condition
+originates. Linking an MIT library to a GPL library implies a policy to share
+the MIT library despite the MIT license having no source sharing requirement.
+
+In this case, one or more resolution tuples will have the MIT license module in
+`ActsOn` and the restricted condition originating at the GPL library module in
+`Resolves`. These tuples will `AttachTo` every target that depends on the GPL
+library because shipping any of those targets trigger the policy to share the
+code.

+// (restricted) conditions down from targets into linked dependencies.
+//
+// 3. Finally, a walk of the shipped target nodes attaches resolutions to the
+// ancestor nodes from the root down to and including the first non-container.
+//
+// e.g. If a disk image contains a binary bin1 that links a library liba, the
+// notice requirement for liba gets attached to the disk image and to bin1.
+// Because liba doesn't actually get shipped as a separate artifact, but only

+// inherited restricted conditions do not propagate from pure aggregates to
+// their dependencies.

+// depending on the types of dependencies involved. All conditions apply across
+// normal derivation dependencies. No conditions apply across toolchain
+// dependencies. Some restricted conditions apply across dynamic link
+// dependencies.

+//
+// i.e. What is the source-sharing policy? Has it been met? Meet it.
+//
+// i.e. Are there incompatible policy requirements? Such as a source-sharing
+// policy applied to code that policy also says may not be shared? If so, stop
+// and remove the dependencies that create the situation.
+//
+// The ResolutionSet is the base unit for mapping license conditions to the
+// targets triggering some necessary action per policy. Different ResolutionSet

+// condition would originate from the .a library. A ResolutionSet for the

+// act on the origin of each condition. By attaching the notice condition to
+// the binary, the ResolutionSet stipulates the policy that the release of the
+// unencumbered binary must provide suitable notice for the .a library.
+//
+// The resulting ResolutionSet could be used for building a notice file, for
+// validating that a suitable notice has been built into the distribution, or
+// for reporting what notices need to be given.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+
+License
+
+THE WORK (AS DEFINED BELOW) IS PROVIDED UNDER THE TERMS OF THIS CREATIVE
+COMMONS PUBLIC LICENSE ("CCPL" OR "LICENSE"). THE WORK IS PROTECTED BY
+COPYRIGHT AND/OR OTHER APPLICABLE LAW. ANY USE OF THE WORK OTHER THAN AS
+AUTHORIZED UNDER THIS LICENSE OR COPYRIGHT LAW IS PROHIBITED.
+
+BY EXERCISING ANY RIGHTS TO THE WORK PROVIDED HERE, YOU ACCEPT AND AGREE TO BE
+BOUND BY THE TERMS OF THIS LICENSE. THE LICENSOR GRANTS YOU THE RIGHTS
+CONTAINED HERE IN CONSIDERATION OF YOUR ACCEPTANCE OF SUCH TERMS AND
+CONDITIONS.
+
+1. Definitions
+
+    "Collective Work" means a work, such as a periodical issue, anthology or
+    encyclopedia, in which the Work in its entirety in unmodified form, along
+    with a number of other contributions, constituting separate and independent
+    works in themselves, are assembled into a collective whole. A work that
+    constitutes a Collective Work will not be considered a Derivative Work (as
+    defined below) for the purposes of this License.
+
+    "Derivative Work" means a work based upon the Work or upon the Work and
+    other pre-existing works, such as a translation, musical arrangement,
+    dramatization, fictionalization, motion picture version, sound recording,
+    art reproduction, abridgment, condensation, or any other form in which the
+    Work may be recast, transformed, or adapted, except that a work that
+    constitutes a Collective Work will not be considered a Derivative Work for
+    the purpose of this License. For the avoidance of doubt, where the Work is
+    a musical composition or sound recording, the synchronization of the Work
+    in timed-relation with a moving image ("synching") will be considered a
+    Derivative Work for the purpose of this License.
+
+    "Licensor" means the individual or entity that offers the Work under the
+    terms of this License.
+
+    "Original Author" means the individual or entity who created the Work.
+
+    "Work" means the copyrightable work of authorship offered under the terms
+    of this License.
+
+    "You" means an individual or entity exercising rights under this License
+    who has not previously violated the terms of this License with respect to
+    the Work, or who has received express permission from the Licensor to
+    exercise rights under this License despite a previous violation.
+
+2. Fair Use Rights. Nothing in this license is intended to reduce, limit, or
+restrict any rights arising from fair use, first sale or other limitations on
+the exclusive rights of the copyright owner under copyright law or other
+applicable laws.
+
+3. License Grant. Subject to the terms and conditions of this License, Licensor
+hereby grants You a worldwide, royalty-free, non-exclusive, perpetual (for the
+duration of the applicable copyright) license to exercise the rights in the
+Work as stated below:
+
+    to reproduce the Work, to incorporate the Work into one or more Collective
+    Works, and to reproduce the Work as incorporated in the Collective Works;
+
+    to create and reproduce Derivative Works;
+
+    to distribute copies or phonorecords of, display publicly, perform
+    publicly, and perform publicly by means of a digital audio transmission the
+    Work including as incorporated in Collective Works;
+
+    to distribute copies or phonorecords of, display publicly, perform
+    publicly, and perform publicly by means of a digital audio transmission
+    Derivative Works.
+
+    For the avoidance of doubt, where the work is a musical composition:
+        Performance Royalties Under Blanket Licenses. Licensor waives the
+        exclusive right to collect, whether individually or via a performance
+        rights society (e.g. ASCAP, BMI, SESAC), royalties for the public
+        performance or public digital performance (e.g. webcast) of the Work.
+
+        Mechanical Rights and Statutory Royalties. Licensor waives the
+        exclusive right to collect, whether individually or via a music rights
+        agency or designated agent (e.g. Harry Fox Agency), royalties for any
+        phonorecord You create from the Work ("cover version") and distribute,
+        subject to the compulsory license created by 17 USC Section 115 of the
+        US Copyright Act (or the equivalent in other jurisdictions).
+
+    Webcasting Rights and Statutory Royalties. For the avoidance of doubt,
+    where the Work is a sound recording, Licensor waives the exclusive right to
+    collect, whether individually or via a performance-rights society (e.g.
+    SoundExchange), royalties for the public digital performance (e.g. webcast)
+    of the Work, subject to the compulsory license created by 17 USC Section
+    114 of the US Copyright Act (or the equivalent in other jurisdictions).
+
+The above rights may be exercised in all media and formats whether now known or
+hereafter devised. The above rights include the right to make such
+modifications as are technically necessary to exercise the rights in other
+media and formats. All rights not expressly granted by Licensor are hereby
+reserved.
+
+4. Restrictions.The license granted in Section 3 above is expressly made
+subject to and limited by the following restrictions:
+
+    You may distribute, publicly display, publicly perform, or publicly
+    digitally perform the Work only under the terms of this License, and You
+    must include a copy of, or the Uniform Resource Identifier for, this
+    License with every copy or phonorecord of the Work You distribute, publicly
+    display, publicly perform, or publicly digitally perform. You may not offer
+    or impose any terms on the Work that alter or restrict the terms of this
+    License or the recipients' exercise of the rights granted hereunder. You
+    may not sublicense the Work. You must keep intact all notices that refer to
+    this License and to the disclaimer of warranties. You may not distribute,
+    publicly display, publicly perform, or publicly digitally perform the Work
+    with any technological measures that control access or use of the Work in a
+    manner inconsistent with the terms of this License Agreement. The above
+    applies to the Work as incorporated in a Collective Work, but this does not
+    require the Collective Work apart from the Work itself to be made subject
+    to the terms of this License. If You create a Collective Work, upon notice
+    from any Licensor You must, to the extent practicable, remove from the
+    Collective Work any credit as required by clause 4(b), as requested. If You
+    create a Derivative Work, upon notice from any Licensor You must, to the
+    extent practicable, remove from the Derivative Work any credit as required
+    by clause 4(b), as requested.
+
+    If you distribute, publicly display, publicly perform, or publicly
+    digitally perform the Work or any Derivative Works or Collective Works, You
+    must keep intact all copyright notices for the Work and provide, reasonable
+    to the medium or means You are utilizing: (i) the name of the Original
+    Author (or pseudonym, if applicable) if supplied, and/or (ii) if the
+    Original Author and/or Licensor designate another party or parties (e.g. a
+    sponsor institute, publishing entity, journal) for attribution in
+    Licensor's copyright notice, terms of service or by other reasonable means,
+    the name of such party or parties; the title of the Work if supplied; to
+    the extent reasonably practicable, the Uniform Resource Identifier, if any,
+    that Licensor specifies to be associated with the Work, unless such URI
+    does not refer to the copyright notice or licensing information for the
+    Work; and in the case of a Derivative Work, a credit identifying the use of
+    the Work in the Derivative Work (e.g., "French translation of the Work by
+    Original Author," or "Screenplay based on original Work by Original
+    Author"). Such credit may be implemented in any reasonable manner;
+    provided, however, that in the case of a Derivative Work or Collective
+    Work, at a minimum such credit will appear where any other comparable
+    authorship credit appears and in a manner at least as prominent as such
+    other comparable authorship credit.
+
+5. Representations, Warranties and Disclaimer
+
+UNLESS OTHERWISE MUTUALLY AGREED TO BY THE PARTIES IN WRITING, LICENSOR OFFERS
+THE WORK AS-IS AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY KIND
+CONCERNING THE WORK, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE, INCLUDING,
+WITHOUT LIMITATION, WARRANTIES OF TITLE, MERCHANTIBILITY, FITNESS FOR A
+PARTICULAR PURPOSE, NONINFRINGEMENT, OR THE ABSENCE OF LATENT OR OTHER DEFECTS,
+ACCURACY, OR THE PRESENCE OF ABSENCE OF ERRORS, WHETHER OR NOT DISCOVERABLE.
+SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF IMPLIED WARRANTIES, SO SUCH
+EXCLUSION MAY NOT APPLY TO YOU.
+
+6. Limitation on Liability. EXCEPT TO THE EXTENT REQUIRED BY APPLICABLE LAW, IN
+NO EVENT WILL LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY FOR ANY SPECIAL,
+INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES ARISING OUT OF THIS
+LICENSE OR THE USE OF THE WORK, EVEN IF LICENSOR HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+7. Termination
+
+    This License and the rights granted hereunder will terminate automatically
+    upon any breach by You of the terms of this License. Individuals or
+    entities who have received Derivative Works or Collective Works from You
+    under this License, however, will not have their licenses terminated
+    provided such individuals or entities remain in full compliance with those
+    licenses. Sections 1, 2, 5, 6, 7, and 8 will survive any termination of
+    this License.
+
+    Subject to the above terms and conditions, the license granted here is
+    perpetual (for the duration of the applicable copyright in the Work).
+    Notwithstanding the above, Licensor reserves the right to release the Work
+    under different license terms or to stop distributing the Work at any time;
+    provided, however that any such election will not serve to withdraw this
+    License (or any other license that has been, or is required to be, granted
+    under the terms of this License), and this License will continue in full
+    force and effect unless terminated as stated above.
+
+8. Miscellaneous
+
+    Each time You distribute or publicly digitally perform the Work or a
+    Collective Work, the Licensor offers to the recipient a license to the Work
+    on the same terms and conditions as the license granted to You under this
+    License.
+
+    Each time You distribute or publicly digitally perform a Derivative Work,
+    Licensor offers to the recipient a license to the original Work on the same
+    terms and conditions as the license granted to You under this License.
+
+    If any provision of this License is invalid or unenforceable under
+    applicable law, it shall not affect the validity or enforceability of the
+    remainder of the terms of this License, and without further action by the
+    parties to this agreement, such provision shall be reformed to the minimum
+    extent necessary to make such provision valid and enforceable.
+
+    No term or provision of this License shall be deemed waived and no breach
+    consented to unless such waiver or consent shall be in writing and signed
+    by the party to be charged with such waiver or consent.
+
+    This License constitutes the entire agreement between the parties with
+    respect to the Work licensed here. There are no understandings, agreements
+    or representations with respect to the Work not specified here. Licensor
+    shall not be bound by any additional provisions that may appear in any
+    communication from You. This License may not be modified without the mutual
+    written agreement of the Licensor and You.
+
+Creative Commons is not a party to this License, and makes no warranty
+whatsoever in connection with the Work. Creative Commons will not be liable to
+You or any party on any legal theory for any damages whatsoever, including
+without limitation any general, special, incidental or consequential damages
+arising in connection to this license. Notwithstanding the foregoing two (2)
+sentences, if Creative Commons has expressly identified itself as the Licensor
+hereunder, it shall have all rights and obligations of Licensor.
+
+Except for the limited purpose of indicating to the public that the Work is
+licensed under the CCPL, neither party will use the trademark "Creative
+Commons" or any related trademark or logo of Creative Commons without the prior
+written consent of Creative Commons. Any permitted use will be in compliance
+with Creative Commons' then-current trademark usage guidelines, as may be

+`fsverity_metadata_generator` generates fsverity metadata and signature to a
+container file
+
+This actually is a simple wrapper around the `fsverity` program. A file is
+signed by the program which produces the PKCS#7 signature file, merkle tree file
+, and the fsverity_descriptor file. Then the files are packed into a single
+output file so that the information about the signing stays together.
+
+Currently, the output of this script is used by `fd_server` which is the host-
+side backend of an authfs filesystem. `fd_server` uses this file in case when
+the underlying filesystem (ext4, etc.) on the device doesn't support the
+fsverity feature natively in which case the information is read directly from
+the filesystem using ioctl.

+"""This script merges two partial target files packages.
+
+One input package contains framework files, and the other contains vendor files.
+
+This script produces a complete, merged target files package:
+  - This package can be used to generate a flashable IMG package.
+    See --output-img.
+  - This package can be used to generate an OTA package. See --output-ota.
+  - The merged package is checked for compatibility between the two inputs.
+
+Usage: merge_target_files [args]
+
+  --framework-target-files framework-target-files-zip-archive
+      The input target files package containing framework bits. This is a zip
+      archive.
+
+  --framework-item-list framework-item-list-file
+      The optional path to a newline-separated config file of items that
+      are extracted as-is from the framework target files package.
+
+  --framework-misc-info-keys framework-misc-info-keys-file
+      The optional path to a newline-separated config file of keys to
+      extract from the framework META/misc_info.txt file.
+
+  --vendor-target-files vendor-target-files-zip-archive
+      The input target files package containing vendor bits. This is a zip
+      archive.
+
+  --vendor-item-list vendor-item-list-file
+      The optional path to a newline-separated config file of items that
+      are extracted as-is from the vendor target files package.
+
+  --output-target-files output-target-files-package
+      If provided, the output merged target files package. Also a zip archive.
+
+  --output-dir output-directory
+      If provided, the destination directory for saving merged files. Requires
+      the --output-item-list flag.
+      Can be provided alongside --output-target-files, or by itself.
+
+  --output-item-list output-item-list-file.
+      The optional path to a newline-separated config file that specifies the
+      file patterns to copy into the --output-dir. Required if providing
+      the --output-dir flag.
+
+  --output-ota output-ota-package
+      The output ota package. This is a zip archive. Use of this flag may
+      require passing the --path common flag; see common.py.
+
+  --output-img output-img-package
+      The output img package, suitable for use with 'fastboot update'. Use of
+      this flag may require passing the --path common flag; see common.py.
+
+  --output-super-empty output-super-empty-image
+      If provided, creates a super_empty.img file from the merged target
+      files package and saves it at this path.
+
+  --rebuild_recovery
+      Copy the recovery image used by non-A/B devices, used when
+      regenerating vendor images with --rebuild-sepolicy.
+
+  --allow-duplicate-apkapex-keys
+      If provided, duplicate APK/APEX keys are ignored and the value from the
+      framework is used.
+
+  --rebuild-sepolicy
+      If provided, rebuilds odm.img or vendor.img to include merged sepolicy
+      files. If odm is present then odm is preferred.
+
+  --vendor-otatools otatools.zip
+      If provided, use this otatools.zip when recompiling the odm or vendor
+      image to include sepolicy.
+
+  --keep-tmp
+      Keep tempoary files for debugging purposes.
+
+  The following only apply when using the VSDK to perform dexopt on vendor apps:
+
+  --framework-dexpreopt-config
+      If provided, the location of framwework's dexpreopt_config.zip.
+
+  --framework-dexpreopt-tools
+      if provided, the location of framework's dexpreopt_tools.zip.
+
+  --vendor-dexpreopt-config
+      If provided, the location of vendor's dexpreopt_config.zip.

-"""This script merges two partial target files packages.
-
-One input package contains framework files, and the other contains vendor files.
-
-This script produces a complete, merged target files package:
-  - This package can be used to generate a flashable IMG package.
-    See --output-img.
-  - This package can be used to generate an OTA package. See --output-ota.
-  - The merged package is checked for compatibility between the two inputs.
-
-Usage: merge_target_files [args]
-
-  --framework-target-files framework-target-files-zip-archive
-      The input target files package containing framework bits. This is a zip
-      archive.
-
-  --framework-item-list framework-item-list-file
-      The optional path to a newline-separated config file that replaces the
-      contents of DEFAULT_FRAMEWORK_ITEM_LIST if provided.
-
-  --framework-misc-info-keys framework-misc-info-keys-file
-      The optional path to a newline-separated config file that replaces the
-      contents of DEFAULT_FRAMEWORK_MISC_INFO_KEYS if provided.
-
-  --vendor-target-files vendor-target-files-zip-archive
-      The input target files package containing vendor bits. This is a zip
-      archive.
-
-  --vendor-item-list vendor-item-list-file
-      The optional path to a newline-separated config file that replaces the
-      contents of DEFAULT_VENDOR_ITEM_LIST if provided.
-
-  --output-target-files output-target-files-package
-      If provided, the output merged target files package. Also a zip archive.
-
-  --output-dir output-directory
-      If provided, the destination directory for saving merged files. Requires
-      the --output-item-list flag.
-      Can be provided alongside --output-target-files, or by itself.
-
-  --output-item-list output-item-list-file.
-      The optional path to a newline-separated config file that specifies the
-      file patterns to copy into the --output-dir. Required if providing
-      the --output-dir flag.
-
-  --output-ota output-ota-package
-      The output ota package. This is a zip archive. Use of this flag may
-      require passing the --path common flag; see common.py.
-
-  --output-img output-img-package
-      The output img package, suitable for use with 'fastboot update'. Use of
-      this flag may require passing the --path common flag; see common.py.
-
-  --output-super-empty output-super-empty-image
-      If provided, creates a super_empty.img file from the merged target
-      files package and saves it at this path.
-
-  --rebuild_recovery
-      Deprecated; does nothing.
-
-  --allow-duplicate-apkapex-keys
-      If provided, duplicate APK/APEX keys are ignored and the value from the
-      framework is used.
-
-  --keep-tmp
-      Keep tempoary files for debugging purposes.
