-       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

-  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">

-      <!-- content here -->
-    </div>
-
-    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.

+
+Generating the android_filesystem_config.h
+
+To generate the android_filesystem_config.h file, one can choose from
+one of two methods. The first method, is to declare
+TARGET_ANDROID_FILESYSTEM_CONFIG_H in the device BoardConfig.mk file. This
+variable can only have one item in it, and it is used directly as the
+android_filesystem_config.h header when building
+fs_config_generate_$(TARGET_DEVICE) which is used to generate fs_config_files
+and fs_config_dirs target executable.
+
+The limitation with this, is that it can only be set once, thus if the device
+has a make hierarchy, then each device needs its own file, and cannot share
+from a common source or that common source needs to include everything from
+both devices.
+
+The other way is to set TARGET_FS_CONFIG_GEN, which can be a list of
+intermediate fs configuration files. It is a build error on any one
+these conditions:
+ * Specify TARGET_FS_CONFIG_GEN and TARGET_ANDROID_FILESYSTEM_CONFIG_H
+ * Specify TARGET_FS_CONFIG_GEN and provide
+   $(TARGET_DEVICE_DIR)/android_filesystem_config.h
+
+The parsing of the config file 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:
+  The exact, C define for a valid AID. Note custom AIDs can be defined in the
+  AID section documented below.
+
+group:
+  The exact, C define for a valid AID. Note custom AIDs can be defined in the
+  AID section documented below.
+
+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]. Per the ini
+specifications enforced by Pythons ConfigParser.
+
+
+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 be any valid character for a #define identifier in C.
+
+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>]. Per the ini
+specifications enforced by Pythons ConfigParser. 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
+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.

-     *    cover every byte of the APK being signed.
-     * 2. Enable much faster signature and integrity verification. This is achieved by requiring
-     *    only a minimal amount of APK parsing before the signature is verified, thus completely
-     *    bypassing ZIP entry decompression and by making integrity verification parallelizable by
-     *    employing a hash tree.
-     *
-     * The generated signature block is wrapped into an APK Signing Block and inserted into the
-     * original APK immediately before the start of ZIP Central Directory. This is to ensure that
-     * JAR and ZIP parsers continue to work on the signed APK. The APK Signing Block is designed for
-     * extensibility. For example, a future signature scheme could insert its signatures there as
-     * well. The contract of the APK Signing Block is that all contents outside of the block must be
-     * protected by signatures inside the block.

+"""Tool to prioritize which modules to convert to Soong.
+
+Generally, you'd use this through the make integration, which automatically
+generates the CSV input file that this tool expects:
+
+  $ m $OUT/soong_to_convert.txt
+  $ less $OUT/soong_to_convert.txt
+
+The output is a list of modules that are probably ready to convert to Soong:
+
+  # Blocked on Module (potential problems)
+           283 libEGL (srcs_dotarm)
+           246 libicuuc (dotdot_incs dotdot_srcs)
+           221 libspeexresampler
+           215 libcamera_metadata
+               ...
+             0 zram-perf (dotdot_incs)
+
+The number at the beginning of the line shows how many native modules depend
+on that module.
+
+All of their dependencies have been satisfied, and any potential problems
+that Make can detect are listed in parenthesis after the module:
+
+  dotdot_srcs: LOCAL_SRC_FILES contains paths outside $(LOCAL_PATH)
+  dotdot_incs: LOCAL_C_INCLUDES contains paths include '..'
+  srcs_dotarm: LOCAL_SRC_FILES contains source files like <...>.c.arm
+  aidl: LOCAL_SRC_FILES contains .aidl sources
+  dbus: LOCAL_SRC_FILES contains .dbus-xml sources
+  objc: LOCAL_SRC_FILES contains Objective-C sources
+  proto: LOCAL_SRC_FILES contains .proto sources
+  rs: LOCAL_SRC_FILES contains renderscript sources
+  vts: LOCAL_SRC_FILES contains .vts sources
+
+Not all problems can be discovered, but this is a starting point.
