 # Build System Changes for Android.mk Writers
 
+## Dexpreopt starts enforcing `<uses-library>` checks (for Java modules)
+
+In order to construct correct class loader context for dexpreopt, build system
+needs to know about the shared library dependencies of Java modules listed in
+the `<uses-library>` tags in the manifest. Since the build system does not have
+access to the manifest contents, that information must be present in the build
+files. In simple cases Soong is able to infer it from its knowledge of Java SDK
+libraries and the `libs` property in Android.bp, but in more complex cases it is
+necessary to add the missing information in Android.bp/Android.mk manually.
+
+To specify a list of libraries for a given modules, use:
+
+* Android.bp properties: `uses_libs`, `optional_uses_libs`
+* Android.mk variables: `LOCAL_USES_LIBRARIES`, `LOCAL_OPTIONAL_USES_LIBRARIES`
+
+If a library is in `libs`, it usually should *not* be added to the above
+properties, and Soong should be able to infer the `<uses-library>` tag. But
+sometimes a library also needs additional information in its
+Android.bp/Android.mk file (e.g. when it is a `java_library` rather than a
+`java_sdk_library`, or when the library name is different from its module name,
+or when the module is defined in Android.mk rather than Android.bp). In such
+cases it is possible to tell the build system that the library provides a
+`<uses-library>` with a given name (however, this is discouraged and will be
+deprecated in the future, and it is recommended to fix the underlying problem):
+
+* Android.bp property: `provides_uses_lib`
+* Android.mk variable: `LOCAL_PROVIDES_USES_LIBRARY`
+
+It is possible to disable the check on a per-module basis. When doing that it is
+also recommended to disable dexpreopt, as disabling a failed check will result
+in incorrect class loader context recorded in the .odex file, which will cause
+class loader context mismatch and dexopt at first boot.
+
+* Android.bp property: `enforce_uses_lib`
+* Android.mk variable: `LOCAL_ENFORCE_USES_LIBRARIES`
+
+Finally, it is possible to globally disable the check:
+
+* For a given product: `PRODUCT_BROKEN_VERIFY_USES_LIBRARIES := true`
+* On the command line: `RELAX_USES_LIBRARY_CHECK=true`
+
+The environment variable overrides the product variable, so it is possible to
+disable the check for a product, but quickly re-enable it for a local build.
+
+## `LOCAL_REQUIRED_MODULES` requires listed modules to exist {#BUILD_BROKEN_MISSING_REQUIRED_MODULES}
+
+Modules listed in `LOCAL_REQUIRED_MODULES`, `LOCAL_HOST_REQUIRED_MODULES` and
+`LOCAL_TARGET_REQUIRED_MODULES` need to exist unless `ALLOW_MISSING_DEPENDENCIES`
+is set.
+
+To temporarily relax missing required modules check, use:
+
+`BUILD_BROKEN_MISSING_REQUIRED_MODULES := true`
+
+## Changes in system properties settings
+
+### Product variables
+
+System properties for each of the partition is supposed to be set via following
+product config variables.
+
+For system partition,
+
+* `PRODUCT_SYSTEM_PROPERTIES`
+* `PRODUCT_SYSTEM_DEFAULT_PROPERTIES` is highly discouraged. Will be deprecated.
+
+For vendor partition,
+
+* `PRODUCT_VENDOR_PROPERTIES`
+* `PRODUCT_PROPERTY_OVERRIDES` is highly discouraged. Will be deprecated.
+* `PRODUCT_DEFAULT_PROPERTY_OVERRIDES` is also discouraged. Will be deprecated.
+
+For odm partition,
+
+* `PRODUCT_ODM_PROPERTIES`
+
+For system_ext partition,
+
+* `PRODUCT_SYSTEM_EXT_PROPERTIES`
+
+For product partition,
+
+* `PRODUCT_PRODUCT_PROPERTIES`
+
+### Duplication is not allowed within a partition
+
+For each partition, having multiple sysprop assignments for the same name is
+prohibited. For example, the following will now trigger an error:
+
+`PRODUCT_VENDOR_PROPERTIES += foo=true foo=false`
+
+Having duplication across partitions are still allowed. So, the following is
+not an error:
+
+`PRODUCT_VENDOR_PROPERTIES += foo=true`
+`PRODUCT_SYSTEM_PROPERTIES += foo=false`
+
+In that case, the final value is determined at runtime. The precedence is
+
+* product
+* odm
+* vendor
+* system_ext
+* system
+
+So, `foo` becomes `true` because vendor has higher priority than system.
+
+To temporarily turn the build-time restriction off, use
+
+`BUILD_BROKEN_DUP_SYSPROP := true`
+
+### Optional assignments
+
+System properties can now be set as optional using the new syntax:
+
+`name ?= value`
+
+Then the system property named `name` gets the value `value` only when there
+is no other non-optional assignments having the same name. For example, the
+following is allowed and `foo` gets `true`
+
+`PRODUCT_VENDOR_PROPERTIES += foo=true foo?=false`
+
+Note that the order between the optional and the non-optional assignments
+doesn't matter. The following gives the same result as above.
+
+`PRODUCT_VENDOR_PROPERTIES += foo?=false foo=true`
+
+Optional assignments can be duplicated and in that case their order matters.
+Specifically, the last one eclipses others.
+
+`PRODUCT_VENDOR_PROPERTIES += foo?=apple foo?=banana foo?=mango`
+
+With above, `foo` becomes `mango` since its the last one.
+
+Note that this behavior is different from the previous behavior of preferring
+the first one. To go back to the original behavior for compatability reason,
+use:
+
+`BUILD_BROKEN_DUP_SYSPROP := true`
+
+## ELF prebuilts in `PRODUCT_COPY_FILES` {#BUILD_BROKEN_ELF_PREBUILT_PRODUCT_COPY_FILES}
+
+ELF prebuilts in `PRODUCT_COPY_FILES` that are installed into these paths are an
+error:
+
+* `<partition>/bin/*`
+* `<partition>/lib/*`
+* `<partition>/lib64/*`
+
+Define prebuilt modules and add them to `PRODUCT_PACKAGES` instead.
+To temporarily relax this check and restore the behavior prior to this change,
+set `BUILD_BROKEN_ELF_PREBUILT_PRODUCT_COPY_FILES := true` in `BoardConfig.mk`.
+
 ## COPY_HEADERS usage now produces warnings {#copy_headers}
 
 We've considered `BUILD_COPY_HEADERS`/`LOCAL_COPY_HEADERS` to be deprecated for

+
+banchan selects individual APEX modules to be built by the Android build system.
+Like "tapas", "banchan" does not request the building of images for a device but
+instead configures it for an unbundled build of the given modules, suitable for
+installing on any api-compatible device.
+
+The difference from "tapas" is that "banchan" sets the appropriate products etc
+for building APEX modules rather than apps (APKs).
+
+The module names should match apex{} modules in Android.bp files, typically
+starting with "com.android.".
+
+The product argument should be a product name ending in "_<arch>", where <arch>
+is one of arm, x86, arm64, x86_64. It can also be just an arch, in which case
+the standard product for building modules with that architecture is used, i.e.
+module_<arch>.
+
+The usage of the other arguments matches that of the rest of the platform
+build system and can be found by running `m help`'

+<h3><a name="unbundled-build"/>Unbundled build</h3>
+<p>Unbundled build has several meanings by the context.
+Let me explain the meaning by the flags related to "unbundled build"</p>
+<h4>TARGET_BUILD_UNBUNDLED</h4>
+<p>The source tree might not have the full platform sources. It is always set if
+<code>TARGET_BUILD_APPS</code> or <code>TARGET_BUILD_UNBUNDLED_IMAGE</code> is set.</p>
+<h4>TARGET_BUILD_USE_PREBUILT_SDKS</h4>
+<p>It is an internal flag. If it is set, prebuilt SDKs are used, even if a module's
+<code>LOCAL_SDK_VERSION</code> is <code>current</code> (including <code>system_current</code>,
+<code>core_current</code>, and so on). If it is unset, build current SDKs,
+and use them as usual.</p>
+<h4>DISABLE_PREOPT</h4>
+<p>It is an internal flag as well. If it is set, dexpreopt is disabled.
+It is always set if <code>TARGET_BUILD_APPS</code> or <code>TARGET_BUILD_UNBUNDLED_IMAGE</code> is set,

+<h4>TARGET_BUILD_UNBUNDLED_IMAGE</h4>
+<p>It is similar to <code>TARGET_BUILD_APPS</code>, but its target is an unbundled partition
+(such as the vendor partition). Accordingly, it sets <code>TARGET_BUILD_UNBUNDLED</code> and <code>DISABLE_PREOPT</code>.
+We can call the partition unbundled, because the partition can be distributed outside the platform.

+A tool for merging dexpreopt.config files for <uses-library> dependencies into
+the dexpreopt.config file of the library/app that uses them. This is needed to
+generate class loader context (CLC) for dexpreopt.
+
+In Make there is no topological order when processing different modules, so a
+<uses-library> dependency module may have not been processed yet by the time the
+dependent module is processed. Therefore makefiles communicate the information
+from dependencies via dexpreopt.config files and add file-level dependencies
+from a module dexpreopt.config to its dependency configs. The actual patching
+of configs is done by this script, which is called from the makefiles.

+
+"""
+This script helps find various build behaviors that make builds less hermetic
+and repeatable. Depending on the flags, it runs a sequence of builds and looks
+for files that have changed or have been improperly regenerated, updating
+their timestamps incorrectly. It also looks for changes that the build has
+done to the source tree, and for files whose contents are dependent on the
+location of the out directory.
+
+This utility has two major modes, full and incremental. By default, this tool
+runs in full mode. To run in incremental mode, pass the --incremental flag.
+
+
+FULL MODE
+
+In full mode, this tool helps verify BUILD CORRECTNESS by examining its
+REPEATABILITY. In full mode, this tool runs two complete builds in different
+directories and compares the CONTENTS of the two directories. Lists of any
+files that are added, removed or changed are printed, sorted by the timestamp
+of that file, to aid finding which dependencies trigger the rebuilding of
+other files.
+
+
+INCREMENTAL MODE
+
+In incremental mode, this tool helps verfiy the SPEED of the build. It runs two
+builds and looks at the TIMESTAMPS of the generated files, and reports files
+that were changed by the second build. In theory, an incremental build with no
+source files touched should not have any generated targets changed. As in full
+builds, the file list is returned sorted by timestamp.
+
+
+OTHER CHECKS
+
+In both full and incremental mode, this tool looks at the timestamps of all
+source files in the tree, and reports on files that have been touched. In the
+output, these are labeled with the header "Source files touched after start of
+build."
+
+In addition, by default, this tool sets the OUT_DIR environment variable to
+something other than "out" in order to find build rules that are not respecting
+the OUT_DIR. If you see these, you should fix them, but if your build can not
+complete for some reason because of this, you can pass the --no-check-out-dir
+flag to suppress this check.
+
+
+OTHER FLAGS
+
+In full mode, the --detect-embedded-paths flag does the two builds in different
+directories, to help in finding rules that embed the out directory path into
+the targets.
+
+The --hide-build-output flag hides the output of successful bulds, to make
+script output cleaner. The output of builds that fail is still shown.
+
+The --no-build flag is useful if you have already done a build and would
+just like to re-run the analysis.
+
+The --target flag lets you specify a build target other than the default
+full build (droid). You can pass "nothing" as in the example below, or a
+specific target, to reduce the scope of the checks performed.
+
+The --touch flag lets you specify a list of source files to touch between
+the builds, to examine the consequences of editing a particular file.
+
+
+EXAMPLE COMMANDLINES
+
+Please run build/make/tools/compare_builds.py --help for a full listing
+of the commandline flags. Here are a sampling of useful combinations.
+
+  1. Find files changed during an incremental build that doesn't build
+     any targets.
+
+       build/make/tools/compare_builds.py --incremental --target nothing
+
+     Long incremental build times, or consecutive builds that re-run build actions
+     are usually caused by files being touched as part of loading the makefiles.
+
+     The nothing build (m nothing) loads the make and blueprint files, generates
+     the dependency graph, but then doesn't actually build any targets. Checking
+     against this build is the fastest and easiest way to find files that are
+     modified while makefiles are read, for example with $(shell) invocations.
+
+  2. Find packaging targets that are different, ignoring intermediate files.
+
+       build/make/tools/compare_builds.py --subdirs --detect-embedded-paths
+
+     These flags will compare the final staging directories for partitions,
+     as well as the APKs, apexes, testcases, and the like (the full directory
+     list is in the DEFAULT_DIRS variable below). Since these are the files
+     that are ultimately released, it is more important that these files be
+     replicable, even if the intermediates that went into them are not (for
+     example, when debugging symbols are stripped).
+
+  3. Check that all targets are repeatable.
+
+       build/make/tools/compare_builds.py --detect-embedded-paths
+
+     This check will list all of the differences in built targets that it can
+     find. Be aware that the AOSP tree still has quite a few targets that
+     are flagged by this check, so OEM changes might be lost in that list.
+     That said, each file shown here is a potential blocker for a repeatable
+     build.
+
+  4. See what targets are rebuilt when a file is touched between builds.
+
+       build/make/tools/compare_builds.py --incremental \
+            --touch frameworks/base/core/java/android/app/Activity.java
+
+     This check simulates the common engineer workflow of touching a single
+     file and rebuilding the whole system. To see a restricted view, consider
+     also passing a --target option for a common use case. For example:
+
+       build/make/tools/compare_builds.py --incremental --target framework \
+            --touch frameworks/base/core/java/android/app/Activity.java

-       GNU GENERAL PUBLIC LICENSE
-           Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.
- 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-          Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.  This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it.  (Some other Free Software Foundation software is covered by
-the GNU Lesser General Public License instead.)  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
-this service 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 make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have.  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.
-
-  We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
-  Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software.  If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary.  To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-        GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License.  The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language.  (Hereinafter, translation is included without limitation in
-the term "modification".)  Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
-  1. You may copy and distribute 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 and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
-  2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) You must cause the modified files to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    b) You must cause any work that you distribute or publish, that in
-    whole or in part contains or is derived from the Program or any
-    part thereof, to be licensed as a whole at no charge to all third
-    parties under the terms of this License.
-
-    c) If the modified program normally reads commands interactively
-    when run, you must cause it, when started running for such
-    interactive use in the most ordinary way, to print or display an
-    announcement including an appropriate copyright notice and a
-    notice that there is no warranty (or else, saying that you provide
-    a warranty) and that users may redistribute the program under
-    these conditions, and telling the user how to view a copy of this
-    License.  (Exception: if the Program itself is interactive but
-    does not normally print such an announcement, your work based on
-    the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-    a) Accompany it with the complete corresponding machine-readable
-    source code, which must be distributed under the terms of Sections
-    1 and 2 above on a medium customarily used for software interchange; or,
-
-    b) Accompany it with a written offer, valid for at least three
-    years, to give any third party, for a charge no more than your
-    cost of physically performing source distribution, a complete
-    machine-readable copy of the corresponding source code, to be
-    distributed under the terms of Sections 1 and 2 above on a medium
-    customarily used for software interchange; or,
-
-    c) Accompany it with the information you received as to the offer
-    to distribute corresponding source code.  (This alternative is
-    allowed only for noncommercial distribution and only if you
-    received the program in object code or executable form with such
-    an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it.  For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable.  However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License.  Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-  5. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Program or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-  6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-  7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-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
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded.  In such case, this License incorporates
-the limitation as if written in the body of this License.
-
-  9. The Free Software Foundation may publish revised and/or new versions
-of the 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 a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation.  If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
-  10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission.  For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this.  Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
-          NO WARRANTY
-
-  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, 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.
-
-  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE 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.

-/**
- * @fileoverview
- * some functions for browser-side pretty printing of code contained in html.
- * <p>
- *
- * For a fairly comprehensive set of languages see the
- * <a href="http://google-code-prettify.googlecode.com/svn/trunk/README.html#langs">README</a>
- * file that came with this source.  At a minimum, the lexer should work on a
- * number of languages including C and friends, Java, Python, Bash, SQL, HTML,
- * XML, CSS, Javascript, and Makefiles.  It works passably on Ruby, PHP and Awk
- * and a subset of Perl, but, because of commenting conventions, doesn't work on
- * Smalltalk, Lisp-like, or CAML-like languages without an explicit lang class.
- * <p>
- * Usage: <ol>
- * <li> include this source file in an html page via
- *   {@code <script type="text/javascript" src="/path/to/prettify.js"></script>}
- * <li> define style rules.  See the example page for examples.
- * <li> mark the {@code <pre>} and {@code <code>} tags in your source with
- *    {@code class=prettyprint.}
- *    You can also use the (html deprecated) {@code <xmp>} tag, but the pretty
- *    printer needs to do more substantial DOM manipulations to support that, so
- *    some css styles may not be preserved.
- * </ol>
- * That's it.  I wanted to keep the API as simple as possible, so there's no
- * need to specify which language the code is in, but if you wish, you can add
- * another class to the {@code <pre>} or {@code <code>} element to specify the
- * language, as in {@code <pre class="prettyprint lang-java">}.  Any class that
- * starts with "lang-" followed by a file extension, specifies the file type.
- * See the "lang-*.js" files in this directory for code that implements
- * per-language file handlers.
- * <p>
- * Change log:<br>
- * cbeust, 2006/08/22
- * <blockquote>
- *   Java annotations (start with "@") are now captured as literals ("lit")
- * </blockquote>

-    * '<script>foo()<\/script>', which would cause the current decorator to
-    * be called with '<script>' which would not match the same rule since
-    * group 1 must not be empty, so it would be instead styled as PR_TAG by
-    * the generic tag rule.  The handler registered for the 'js' extension would
-    * then be called with 'foo()', and finally, the current decorator would
-    * be called with '<\/script>' which would not match the original rule and
-    * so the generic tag rule would identify it as a tag.
-    *
-    * Pattern must only match prefixes, and if it matches a prefix, then that
-    * match is considered a token with the same style.
-    *
-    * Context is applied to the last non-whitespace, non-comment token

-  Fullscreen Carousel
-
-  The following allows for an area at the top of the page that takes over the
-  entire browser height except for its top offset and an optional bottom
-  padding specified as a data attribute.
-
-  HTML:
-
-  <div class="fullscreen-carousel">

-
-    etc ...
-
-  </div>
-
-  Control over how the carousel takes over the screen can mostly be defined in
-  a css file. Setting min-height on the .fullscreen-carousel-content elements
-  will prevent them from shrinking to far vertically when the browser is very
-  short, and setting max-height on the .fullscreen-carousel itself will prevent
-  the area from becoming to long in the case that the browser is stretched very
-  tall.
-
-  There is limited functionality for having multiple sections since that request
-  was removed, but it is possible to add .next-arrow and .prev-arrow elements to
-  scroll between multiple content areas.

-The fs_config_generator.py tool uses the platform android_filesystem_config.h and the
-TARGET_FS_CONFIG_GEN files to generate the fs_config_dirs and fs_config_files files for each
-partition, as well as passwd and group files, and the generated_oem_aid.h header.
-
-The fs_config_dirs and fs_config_files binary files are interpreted by the libcutils fs_config()
-function, along with the built-in defaults, to serve as overrides to complete the results. The
-Target files are used by filesystem and adb tools to ensure that the file and directory properties
-are preserved during runtime operations. The host files in the ${OUT} directory are used in the
-final stages when building the filesystem images to set the file and directory properties.
-
-See ./fs_config_generator.py fsconfig --help for how these files are generated.
-
-The passwd and group files are formatted as documented in man pages passwd(5) and group(5) and used
-by bionic for implementing getpwnam() and related functions.
-
-See ./fs_config_generator.py passwd --help and ./fs_config_generator.py group --help for how these
-files are generated.
-
-The generated_oem_aid.h creates identifiers for non-platform AIDs for developers wishing to use them
-in their native code.  To do so, include the oemaids_headers header library in the corresponding
-makefile and #include "generated_oem_aid.h" in the code wishing to use these identifiers.
-
-See ./fs_config_generator.py oemaid --help for how this file is generated.
-
-The parsing of the TARGET_FS_CONFIG_GEN files follows the Python ConfigParser specification, with
-the sections and fields as defined below. There are two types of sections, both sections require all
-options to be specified. The first section type is the "caps" section.
-
-The "caps" section follows the following syntax:
-
-[path]
-mode: Octal file mode
-user: AID_<user>
-group: AID_<group>
-caps: cap*
-
-Where:
-
-[path]
-  The filesystem path to configure. A path ending in / is considered a dir,
-  else its a file.
-
-mode:
-  A valid octal file mode of at least 3 digits. If 3 is specified, it is
-  prefixed with a 0, else mode is used as is.
-
-user:
-  Either the C define for a valid AID or the friendly name. For instance both
-  AID_RADIO and radio are acceptable. Note custom AIDs can be defined in the
-  AID section documented below.
-
-group:
-  Same as user.
-
-caps:
-  The name as declared in
-  system/core/include/private/android_filesystem_capability.h without the
-  leading CAP_. Mixed case is allowed. Caps can also be the raw:
-   * binary (0b0101)
-   * octal (0455)
-   * int (42)
-   * hex (0xFF)
-  For multiple caps, just separate by whitespace.
-
-It is an error to specify multiple sections with the same [path] in different
-files. Note that the same file may contain sections that override the previous
-section in Python versions <= 3.2. In Python 3.2 it's set to strict mode.
-
-
-The next section type is the "AID" section, for specifying OEM specific AIDS.
-
-The AID section follows the following syntax:
-
-[AID_<name>]
-value: <number>
-
-Where:
-
-[AID_<name>]
-  The <name> can contain characters in the set uppercase, numbers
-  and underscores.
-
-value:
-  A valid C style number string. Hex, octal, binary and decimal are supported.
-  See "caps" above for more details on number formatting.
-
-It is an error to specify multiple sections with the same [AID_<name>]. With
-the same constraints as [path] described above. It is also an error to specify
-multiple sections with the same value option. It is also an error to specify a
-value that is outside of the inclusive OEM ranges:
- * AID_OEM_RESERVED_START(2900) - AID_OEM_RESERVED_END(2999)
- * AID_OEM_RESERVED_2_START(5000) - AID_OEM_RESERVED_2_END(5999)
-
-as defined by system/core/include/private/android_filesystem_config.h.
-
-Ordering within the TARGET_FS_CONFIG_GEN files is not relevant. The paths for files are sorted
-like so within their respective array definition:
- * specified path before prefix match
- ** ie foo before f*
- * lexicographical less than before other
- ** ie boo before foo
-
-Given these paths:
-
-paths=['ac', 'a', 'acd', 'an', 'a*', 'aa', 'ac*']
-
-The sort order would be:
-paths=['a', 'aa', 'ac', 'acd', 'an', 'ac*', 'a*']
-
-Thus the fs_config tools will match on specified paths before attempting prefix, and match on the
-longest matching prefix.
-
-The declared AIDS are sorted in ascending numerical order based on the option "value". The string

+# FS Config Generator
+
+The `fs_config_generator.py` tool uses the platform `android_filesystem_config.h` and the
+`TARGET_FS_CONFIG_GEN` files to generate the following:
+* `fs_config_dirs` and `fs_config_files` files for each partition
+* `passwd` and `group` files for each partition
+* The `generated_oem_aid.h` header
+
+## Outputs
+
+### `fs_config_dirs` and `fs_config_files`
+
+The `fs_config_dirs` and `fs_config_files` binary files are interpreted by the libcutils
+`fs_config()` function, along with the built-in defaults, to serve as overrides to complete the
+results. The Target files are used by filesystem and adb tools to ensure that the file and directory
+properties are preserved during runtime operations. The host files in the `$OUT` directory are used
+in the final stages when building the filesystem images to set the file and directory properties.
+
+See `./fs_config_generator.py fsconfig --help` for how these files are generated.
+
+### `passwd` and `group` files
+
+The `passwd` and `group` files are formatted as documented in man pages passwd(5) and group(5) and
+used by bionic for implementing `getpwnam()` and related functions.
+
+See `./fs_config_generator.py passwd --help` and `./fs_config_generator.py group --help` for how
+these files are generated.
+
+### The `generated_oem_aid.h` header
+
+The `generated_oem_aid.h` creates identifiers for non-platform AIDs for developers wishing to use
+them in their native code.  To do so, include the `oemaids_headers` header library in the
+corresponding makefile and `#include "generated_oem_aid.h"` in the code wishing to use these
+identifiers.
+
+See `./fs_config_generator.py oemaid --help` for how this file is generated.
+
+## Parsing
+
+See the documentation on [source.android.com](https://source.android.com/devices/tech/config/filesystem#configuring-aids) for details and examples.
+
+
+## Ordering
+
+Ordering within the `TARGET_FS_CONFIG_GEN` files is not relevant. The paths for files are sorted
+like so within their respective array definition:
+ * specified path before prefix match
+   * for example: foo before f*
+ * lexicographical less than before other
+   * for example: boo before foo
+
+Given these paths:
+
+    paths=['ac', 'a', 'acd', 'an', 'a*', 'aa', 'ac*']
+
+The sort order would be:
+
+    paths=['a', 'aa', 'ac', 'acd', 'an', 'ac*', 'a*']
+
+Thus the `fs_config` tools will match on specified paths before attempting prefix, and match on the
+longest matching prefix.
+
+The declared AIDs are sorted in ascending numerical order based on the option "value". The string
+representation of value is preserved. Both choices were made for maximum readability of the
+generated file and to line up files. Sync lines are placed with the source file as comments in the
+generated header file.
+
+## Unit Tests
+
+From within the `fs_config` directory, unit tests can be executed like so:
+
+    $ python -m unittest test_fs_config_generator.Tests
+    .............
+    ----------------------------------------------------------------------
+    Ran 13 tests in 0.004s
+
+    OK
+
+One could also use nose if they would like:
+
+    $ nose2
+
+To add new tests, simply add a `test_<xxx>` method to the test class. It will automatically
+get picked up and added to the test suite.

+# Roboleaf configuration files interpreter
+
+Reads and executes Roboleaf product configuration files.
+
+## Usage
+
+`rbcrun` *options* *VAR=value*... [ *file* ]
+
+A Roboleaf configuration file is a Starlark script. Usually it is read from *file*. The option `-c` allows to provide a
+script directly on the command line. The option `-f` is there to allow the name of a file script to contain (`=`).
+(i.e., `my=file.rbc` sets `my` to `file.rbc`, `-f my=file.rbc` runs the script from `my=file.rbc`).
+
+### Options
+
+`-d` *dir*\
+Root directory for load("//path",...)
+
+`-c` *text*\
+Read script from *text*
+
+`--perf` *file*\
+Gather performance statistics and save it to *file*. Use \
+`       go tool prof -top`*file*\
+to show top CPU users
+
+`-f` *file*\
+File to run.
+
+## Extensions
+
+The runner allows Starlark scripts to use the following features that Bazel's Starlark interpreter does not support:
+
+### Load statement URI
+
+Starlark does not define the format of the load statement's first argument.
+The Roboleaf configuration interpreter supports the format that Bazel uses
+(`":file"` or `"//path:file"`). In addition, it allows the URI to end with
+`"|symbol"` which defines a single variable `symbol` with `None` value if a
+module does not exist. Thus,
+
+```
+load(":mymodule.rbc|init", mymodule_init="init")
+```
+
+will load the module `mymodule.rbc` and export a symbol `init` in it as
+`mymodule_init` if `mymodule.rbc` exists. If `mymodule.rbc` is missing,
+`mymodule_init` will be set to `None`
+
+### Predefined Symbols
+
+#### rblf_env
+
+A `struct` containing environment variables. E.g., `rblf_env.USER` is the username when running on Unix.
+
+#### rblf_cli
+
+A `struct` containing the variable set by the interpreter's command line. That is, running
+
+```
+rbcrun FOO=bar myfile.rbc
+```
+
+will have the value of `rblf_cli.FOO` be `"bar"`
+
+### Predefined Functions
+
+#### rblf_file_exists(*file*)
+
+Returns `True`  if *file* exists
+
+#### rblf_wildcard(*glob*, *top* = None)
+
+Expands *glob*. If *top* is supplied, expands "*top*/*glob*", then removes
+"*top*/" prefix from the matching file names.
+
+#### rblf_regex(*pattern*, *text*)
+
+Returns *True* if *text* matches *pattern*.
+
+#### rblf_shell(*command*)
+
+Runs `sh -c "`*command*`"`, reads its output, converts all newlines into spaces, chops trailing newline returns this
+string. This is equivalent to Make's
+`shell` builtin function. *This function will be eventually removed*.
