+2005-02-17  Chris Larson <kergoth@handhelds.org>
+
+	* src/backend-sqlite3.c, include/bitbake-data.h: Adjust the API so
+	  that bitbake-data users aren't required to link against glib-2.0
+	  themselves.
+
+2005-02-03  Chris Larson <kergoth@handhelds.org>
+
+	* doc/doxygen.cfg, doc/doxygen.m4, doc/Makefile.am, configure.ac,
+	  Makefile.am: Add doxygen doc generation.
+	* include/bitbake-data.h, src/backend-sqlite3.h: Add datastore process
+	  wide initialization and shutdown based on usage count.
+	* src/backend-sqlite3.h: Add calls to sqlite3 to open and close the
+	  recipe database.
+	* src/backend-sqlite3.h, include/bitbake-data.h: Adjust the
+	  bb_data_destroy function.  Now accepts a new gboolean
+	  parameter to indicate that the data can be truly removed -- only
+	  affects behavior of stores which are persistant.  Setting said
+	  parameter to TRUE will remove the data for the recipe in question
+	  from the persistant store completely, rather than just freeing our
+	  datastructures.
+	* bitbake-data-0.0.pc.in, bitbake-data.pc.in: Renamed.
+	* configure.ac: Update per .pc.in rename.
+	* Makefile.am: Create a .pc based on LT_RELEASE, and install our .pc.
+	* src/Makefile.am: Don't hardcode the library release.  Use
+	  @LT_RELEASE@ where appropriate instead.
+	* README, AUTHORS: New file.
+	* configure.ac, Makefile.am, tests/Makefile.am, tests/check_bitbake_data.c:
+	  Add the first of our unit tests using 'check'.
+	* src/backend-sqlite3.c, include/bitbake-data/private.h, tests/check_bitbake_data.c:
+	  Add the variable and variable attribute lookup, insertion, and
+	  removal routines.
+	* src/backend-sqlite3.c, tests/check_bitbake_data.c: Start rework of
+	  sqlite tables to accomidate scope resolution.
+
+2005-02-02  Chris Larson <kergoth@handhelds.org>
+
+	* Many files: Created initial repository.
+	* include/bitbake-data/common.h: Add common header for things like gcc
+	  visibility macros.
+	* doc/REQUIREMENTS: Add musings on requirements.

+TODO List
+---------
+NOTE: This is a very simple library with a specific purpose in mind, but we want to
+make sure it's done right, since performance or scalability problems could impact the
+entirety of bitbake and bitbake-ng. --CML
+
+[ ] Fix up the API to accomidate proper error handling, in order to respond to the user
+    and let them know what's going on.  A common problem would be not having write access
+    to the default BBDATAPATH.  Perhaps a more sane default for a normal user would be a
+    file in /var/tmp.
+[ ] Test repeatedly the basic variable set/get/delete operations.
+[ ] Document whether or not the set functions copy the strings of the key/value or use
+    them as is, in the doxygen markup.
+[ ] Code/test/sanity check variable attribute operations.
+[ ] Code/test the last modif date function.
+[ ] Profile the code to ensure it will meet our needs.
+[ ] If necessary, optimize the bottlenecks.
+[ ] Add functions to supply optimization hints to the datastore.  This is almost certain
+    to be necessary, as writes to sqlite are quickest when done in a single transaction.
+    So, you'd have a function stating that you'll be using this heavily for a while, as
+    a hint that perhaps it should be keeping it in RAM until you're done, or postpone
+    COMMIT until you're done.
+[ ] Start using it.

+[ ] Key/value pairs, as close to O(1) as is possible
+[ ] "Attributes".. that is, metadata about our metadata
+[ ] Each store of metadata is bound to a recipe, and we need a way for the
+    recipe handler to deal with the determination of whether the information
+    in the metadata store is current.  Either it asks the store for a last
+    modification date, or the other way around.
+
+[ ] Persistance?  Is persistance a requirement or an optimization?
+    Really, it's an optimization.  If the metadata store isn't persistant,
+    then we need to use whatever other intermediate form is available (i.e.
+    compiled form) to repopulate it on every execution.
+
+    So it isn't a requirement, but the recipe handler needs to be able to
+    determine whether the bitbake-data store in question is up to date or not.
+
+    Perhaps something as simple as a "last modification" date would do.
+
+[ ] If it is persistant, where is the persistant form stored?  Who makes that
+    decision?  A variable in the store itself?  The recipe handler via a function
+    call?  This data really is specific to a certain bitbake recipe or set of
+    bitbake recipes.  We could probably store this in /var/ if we're careful
+    about tracking the sources of the data.
+
+    We have to track what bitbake recipe this data belongs to regardless.  Either
+    one big sqlite3 db, or a bunch of individual files, the info we have to track
+    remains the same.  The choice of implementation just comes down to efficiency.
+
+[ ] Do we really need more than one backend module at runtime, or would compiletime
+    suffice?  Are the needs for metadata handling between recipe handlers the same?
+    And if not, how does the recipe handler go about choosing a metadata module?  Or
+    should that be in the hands of the user?  I'm voting for a single compiletime
+    module, so it's easy to replace later, but without having to deal with module
+    selection at runtime.

+# The provided goals are:
+# doxygen-doc: Generate all doxygen documentation.
+# doxygen-run: Run doxygen, which will generate some of the documentation
+#              (HTML, CHM, CHI, MAN, RTF, XML) but will not do the post
+#              processing required for the rest of it (PS, PDF, and some MAN).
+# doxygen-man: Rename some doxygen generated man pages.
+# doxygen-ps: Generate doxygen PostScript documentation.
+# doxygen-pdf: Generate doxygen PDF documentation.
+#
+# Note that by default these are not integrated into the automake goals. If
+# doxygen is used to generate man pages, you can achieve this integration by
+# setting man3_MANS to the list of man pages generated and then adding the
+# dependency:

+#   $(man3_MANS): doxygen-doc

+# This will cause make to run doxygen and generate all the documentation.

+# Copyright (C) 2004 Oren Ben-Kiki
+# This file is distributed under the same terms as the Autoconf macro files.
+
+# Generate automatic documentation using Doxygen. Works in concert with the
+# aminclude.m4 file and a compatible doxygen configuration file. Defines the
+# following public macros:
+#
+# DX_???_FEATURE(ON|OFF) - control the default setting fo a Doxygen feature.
+# Supported features are 'DOXYGEN' itself, 'DOT' for generating graphics,
+# 'HTML' for plain HTML, 'CHM' for compressed HTML help (for MS users), 'CHI'
+# for generating a seperate .chi file by the .chm file, and 'MAN', 'RTF',
+# 'XML', 'PDF' and 'PS' for the appropriate output formats. The environment
+# variable DOXYGEN_PAPER_SIZE may be specified to override the default 'a4wide'
+# paper size.
+#
+# By default, HTML, PDF and PS documentation is generated as this seems to be
+# the most popular and portable combination. MAN pages created by Doxygen are
+# usually problematic, though by picking an appropriate subset and doing some
+# massaging they might be better than nothing. CHM and RTF are specific for MS
+# (note that you can't generate both HTML and CHM at the same time). The XML is
+# rather useless unless you apply specialized post-processing to it.
+#
+# The macro mainly controls the default state of the feature. The use can
+# override the default by specifying --enable or --disable. The macros ensure
+# that contradictory flags are not given (e.g., --enable-doxygen-html and
+# --enable-doxygen-chm, --enable-doxygen-anything with --disable-doxygen, etc.)
+# Finally, each feature will be automatically disabled (with a warning) if the
+# required programs are missing.
+#
+# Once all the feature defaults have been specified, call DX_INIT_DOXYGEN with
+# the following parameters: a one-word name for the project for use as a
+# filename base etc., an optional configuration file name (the default is
+# 'Doxyfile', the same as Doxygen's default), and an optional output directory
+# name (the default is 'doxygen-doc').

+	  update vim modeline to set the filetype to 'docbk'.
+
+2005-01-13 Chris Larson <kergoth@handhelds.org>
+
+	* Minor rearranging.. now we have m4/internal and m4/external,

+	  machines without 'check' installed.
+
+2005-01-10 Chris Larson <kergoth@handhelds.org>
+
+	* Update library linking so that the dev symlink is
+	  libbitbake-[release].so rather than libbitbake.so.
+
+2005-01-09 Chris Larson <kergoth@handhelds.org>
+
+	* Correct library linking to set libtool's versioning.
+	* Add 'test' target to makefiles, which runs the 'check' unit tests.
+	* Add pkgconfig .pc file.
+
+2005-01-08 Chris Larson <kergoth@handhelds.org>
+
+	* Improve documentation generation.  Use a decent set of
+	  autoconf macros to handle selection of the types of
+	  doxygen output (taken from the "doxample" project).
+	* Use 'check' (http://check.sourceforge.net/) for unit testing.
+	* Add basic variable insert/remove/lookup implementations for the
+	  bitbake metadata (RAM backed for now).
+
+2004-12-30  Chris Larson <kergoth@handhelds.org>
+
+	* Create initial tree for bitbake-ng.
+	* Add autoconf macros for gcc 4.0 (and patched 3.4.x) symbol visibility.
+	* Add initial BitBake-ng Design Specification document.

+        <para>It is said that a developer should always plan on at least one rewrite in a given project.  Such is the case here.  This document outlines the design of bitbake 2.0, the upcoming rewrite of the BitBake project.  It is expected that the reader will have at least a passing familiarity with the bitbake project.  I would recommend perusing the <ulink url="http://bitbake.berlios.de/manual/">bitbake users manual</ulink> if this is not the case.</para>

+                <para>A bitbake recipe consists of a number of individual pieces.  Naturally, being a recipe, it has a set of ordered steps to be followed.  It also has a set of ingredients (associated bitbake metadata).  The first of the bitbake specific aspects of the recipe is that it has links to its <quote>parents</quote>.  The parents of a given bitbake recipe are essentially the context for the recipe, or the <quote>scope</quote> the recipe is in.  This may be global user specified configuration parameters, or <quote>classes</quote> to abstract out common parts of the recipe.  To give a real world example, you might have a recipe class for cookies.  Each recipe has its own unique steps, but for the most part, the steps involved in making cookies are the same.</para>

+# This file is distributed under the same terms as the Automake macro files.
+
+# Generate automatic documentation using Doxygen. Goals and variables values
+# are controlled by the various DX_COND_??? conditionals set by autoconf.
+#
+# The provided goals are:
+# doxygen-doc: Generate all doxygen documentation.
+# doxygen-run: Run doxygen, which will generate some of the documentation
+#              (HTML, CHM, CHI, MAN, RTF, XML) but will not do the post
+#              processing required for the rest of it (PS, PDF, and some MAN).
+# doxygen-man: Rename some doxygen generated man pages.
+# doxygen-ps: Generate doxygen PostScript documentation.
+# doxygen-pdf: Generate doxygen PDF documentation.
+#
+# Note that by default these are not integrated into the automake goals. If
+# doxygen is used to generate man pages, you can achieve this integration by
+# setting man3_MANS to the list of man pages generated and then adding the
+# dependency:
+#
+#   $(man3_MANS): doxygen-doc
+#
+# This will cause make to run doxygen and generate all the documentation.
+#
+# The following variable is intended for use in Makefile.am:
+#
+# DX_CLEANFILES = everything to clean.
+#
+# This is usually added to MOSTLYCLEANFILES.

+	BB_VAR_SET,
+	BB_VAR_APPEND,
+	BB_VAR_APPEND_NOSPACE,

+	BB_VAR_DEL

+	BB_VAR_ATTR_PREPEND_NOSPACE,

+
+struct bb_compiled {
+	list of struct bbc's;
+}
+
+struct pre_metadata_set {
+	list of:
+	{
+		if resolved -> struct var
+		if unresolved -> bbc
+	}
+}
+
+struct metadata_set {
+	parents; /* links to higher scopes */
+	hash table of var name -> struct var;
+}
+
+NOTE: we track variable referrers (who has me in their var chunks?)
+
+example:
+A := ${B} /* unresolved */
+C := a /* resolved */
+D := ${A} /* unresolved */
+C += ${B} /* unresolved */
+E := ${C} /* resolved */
+F = ${B} /* unresolved, but its contents can be a struct var, not an bbc */
+
+Then, when you link a metadata set to another (set our scope under his),
+all the unresolved bbc's can be immediately executed, producing a new
+metadata set which is entirely struct var's.
+
+Once a pre metadata set is executed / attached to its parent scopes, we know
+that the pre_metadata_set -> metadata_set needs to occur again whenever one of
+its parents is dirtied.  Technically, we know which variables in its parents
+affect which variables of ours, but unless we track which bbc's affected which
+variables, we'll have to rerun the pre metadata set -> metadata set operation
+whenever its parents change.
+
+In conclusion, precompiling the .bb with bbc's, and using the pre metadata set,
+enables us to avoid reparsing files that depend on their context in each possible
+context, and when its context changes.  For example, this will enable us to
+avoid reparsing all the .bb files when bb.conf or local.conf changes.
+
+Caching the pre metadata set as well as the compiled bb reduces the number of
+bbc executions necessary when attaching to a new parent scope (i.e. taking
+base.bbclass and attaching it to each and every .bb).
+
+Caching the metadata set allows us to avoid reexecution of any bbc's when
+context hasn't changed, and the compiled bb isnt dirty.
+
+bbmake runs:
+	reparse any changed/new files
+	re execution bbc's whereever someone was affected by the reparses
+	store the metadata sets in an sqlite db
+
+	Now, after this, we know that the db contains the current metadata sets for
+	all existing files.  We can issue sql queries to obtain all the dependency
+	information to construct our build paths, and can obtain the package data
+	whenever we're ready for it.

+# DX_???_FEATURE(ON|OFF) - control the default setting fo a Doxygen feature.
+# Supported features are 'DOXYGEN' itself, 'DOT' for generating graphics,

+# for generating a seperate .chi file by the .chm file, and 'MAN', 'RTF',

+Changes in bitbake 1.3.0:
+	- add bitbake interactive shell (bitbake -i)
+	- refactor bitbake utility in OO style
+	- kill default arguments in methods in the bb.data module
+	- kill default arguments in methods in the bb.fetch module
+	- the http/https/ftp fetcher will fail if the to be 
+	  downloaded file was not found in DL_DIR (this is needed
+	  to avoid unpacking the sourceforge mirror page)
+	- Switch to a cow like data instance for persistent and non
+	  persisting mode (called data_smart.py)
+	- Changed the callback of bb.make.collect_bbfiles to carry
+	  additional parameters
+	- Drastically reduced the amount of needed RAM by not holding
+	  each data instance in memory when using a cache/persistent
+	  storage
+
+Changes in bitbake 1.2.1:
+	The 1.2.1 release is meant as a intermediate release to lay the
+ground for more radical changes. The most notable changes are:
+
+	-Do not hardcode {}, use bb.data.init() instead if you want to
+get a instance of a data class
+	-bb.data.init() is a factory and the old bb.data methods are delegates
+	-Do not use deepcopy use bb.data.createCopy() instead.
+	-Removed default arguments in bb.fetch

+On popular request by popular people a list of tasks to-do:
+
+	-Kill insecure usage of os.system either by properly escaping
+         the strings or a faster replacement not involving /bin/sh
+	-Introduce a -p option to automatically hotshot/profile the
+	 run
+	-Cache dependencies separately and invalidate them when any file
+         changed.
+	-...
+
+
+DONE:
+·       -On generating the inter package deps do not parse each file multiply
+·        times.
+	-We build the lists while parsing the data now
+·       (WAS: Do not generate the world dependency tree, only when someone
+·             requests it.

+		    GNU GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+     59 Temple Place, Suite 330, Boston, MA  02111-1307  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 Library 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.
+
+		     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
+convey 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 2 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, write to the Free Software
+    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year  name of author
+    Gnomovision 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, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This 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 Library General
+Public License instead of this License.

+            <title>Overview</title>
+            <para>BitBake is, at its simplest, a tool for executing
+tasks and managing metadata.  As such, its similarities to GNU make and other
+build tools are readily apparent.  It was inspired by Portage, the package management system used by the Gentoo Linux distribution.  BitBake is the basis of the <ulink url="http://www.openembedded.org/">OpenEmbedded</ulink> project, which is being used to build and maintain a number of embedded Linux distributions, including OpenZaurus and Familiar.</para>

+        <section>
+            <title>Background and Goals</title>
+            <para>Prior to BitBake, no other build tool adequately met
+the needs of an aspiring embedded Linux distribution.  All of the
+buildsystems used by traditional desktop Linux distributions lacked
+important functionality, and none of the ad-hoc
+<emphasis>buildroot</emphasis> systems, prevalent in the
+embedded space, were scalable or maintainable.</para>
+
+      <para>Some important goals for BitBake were:
+            <itemizedlist>
+                <listitem><para>Handle crosscompilation.</para></listitem>
+                <listitem><para>Handle interpackage dependencies (build time on target architecture, build time on native architecture, and runtime).</para></listitem>
+                <listitem><para>Support running any number of tasks within a given package, including, but not limited to, fetching upstream sources, unpacking them, patching them, configuring them, et cetera.</para></listitem>
+                <listitem><para>Must be linux distribution agnostic (both build and target).</para></listitem>
+                <listitem><para>Must be architecture agnostic</para></listitem>
+                <listitem><para>Must support multiple build and target operating systems (including cygwin, the BSDs, etc).</para></listitem>
+                <listitem><para>Must be able to be self contained, rather than tightly integrated into the build machine's root filesystem.</para></listitem>
+                <listitem><para>There must be a way to handle conditional metadata (on target architecture, operating system, distribution, machine).</para></listitem>
+                <listitem><para>It must be easy for the person using the tools to supply their own local metadata and packages to operate against.</para></listitem>
+                <listitem><para>Must make it easy to collaborate
+between multiple projects using BitBake for their
+builds.</para></listitem>
+		<listitem><para>Should provide an inheritance mechanism to
+share common metadata between many packages.</para></listitem>
+                <listitem><para>Et cetera...</para></listitem>
+            </itemizedlist>
+        </para>
+        <para>BitBake satisfies all these and many more.  Flexibility and power have always been the priorities.  It is highly extensible, supporting embedded Python code and execution of any arbitrary tasks.</para>

+                <para>BitBake metadata can be classified into 3 major areas:</para>

+                <title>Immediate variable expansion (:=)</title>
+                <para>:= results in a variable's contents being expanded immediately, rather than when the variable is actually used.</para>

+                <para>OVERRIDES is a <quote>:</quote> seperated variable containing each item you want to satisfy conditions.  So, if you have a variable which is conditional on <quote>arm</quote>, and <quote>arm</quote> is in OVERRIDES, then the <quote>arm</quote> specific version of the variable is used rather than the non-conditional version.  Example:</para>
+                <para><screen><varname>OVERRIDES</varname> = "architecture:os:machine"
+<varname>TEST</varname> = "defaultvalue"

+                <para>In this example, <varname>TEST</varname> would be <literal>osspecificvalue</literal>, due to the condition <quote>os</quote> being in <varname>OVERRIDES</varname>.</para>

+                <para>BitBake also supports appending and prepending to variables based on whether something is in OVERRIDES.  Example:</para>

+<varname>OVERRIDES</varname> = "machine:local"

+                <para>Next, there is the <literal>include</literal> directive, which causes BitBake to parse in whatever file you specify, and insert it at that location, which is not unlike <command>make</command>.  However, if the path specified on the <literal>include</literal> line is a relative path, BitBake will locate the first one it can find within <envar>BBPATH</envar>.</para>

A given bbclass is located by searching for classes/filename.oeclass in <envar>BBPATH</envar>, where filename is what you inherited.</para>

This metadata is global, and therefore affects <emphasis>all</emphasis> packages and tasks which are executed.  Currently, BitBake has hardcoded knowledge of a single configuration file.  It expects to find 'conf/bitbake.conf' somewhere in the user specified <envar>BBPATH</envar>.  That configuration file generally has include directives to pull in any other metadata (generally files specific to architecture, machine, <emphasis>local</emphasis> and so on.</para>

+usage: bitbake [options] [package ...]
+
+Executes the specified task (default is 'build') for a given set of BitBake files.
+It expects that BBFILES is defined, which is a space seperated list of files to
+be executed.  BBFILES does support wildcards.
+Default BBFILES are the .bb files in the current directory.
+
+options:
+  --version             show program's version number and exit
+  -h, --help            show this help message and exit
+  -bBUILDFILE, --buildfile=BUILDFILE
+                        execute the task against this .bb file, rather than a
+                        package from BBFILES.
+  -k, --continue        continue as much as possible after an error. While the
+                        target that failed, and those that depend on it, cannot
+                        be remade, the other dependencies of these targets can
+                        be processed all the same.
+  -f, --force           force run of specified cmd, regardless of stamp status
+  -cCMD, --cmd=CMD      Specify task to execute
+  -rFILE, --read=FILE   read the specified file before bitbake.conf
+  -v, --verbose         output more chit-chat to the terminal
+  -D, --debug           Increase the debug level
+  -n, --dry-run         don't execute, just go through the motions
+  -p, --parse-only      quit after parsing the BB files (developers only)
+  -d, --disable-psyco   disable using the psyco just-in-time compiler (not
+                        recommended)
+  -s, --show-versions   show current and preferred versions of all packages</screen>

+                    <para>There are a number of additional complexities introduced when one wants to manage multiple .bb files.  Clearly there needs to be a way to tell bitbake what files are available, and of those, which we want to execute at this time.  There also needs to be a way for each .bb to express its dependencies, both for build time and runtime.  There must be a way for the user to express their preferences when multiple .bb's provide the same functionality, or when there are multiple versions of a .bb.</para>

+                    <para>Note that the bitbake command, when not using --buildfile, accepts a <varname>PROVIDER</varname>, not a filename or anything else.  By default, a .bb generally PROVIDES its packagename, packagename-version, and packagename-version-revision.</para>

+                <para>With regard to dependencies, it expects the .bb to define a <varname>DEPENDS</varname> variable, which contains a space seperated list of <quote>package names</quote>, which themselves are the <varname>PN</varname> variable.  The <varname>PN</varname> variable is, in general, by default, set to a component of the .bb filename.</para>

+BitBake Shell
+
+IDEAS:
+    * list defined tasks per package
+    * list classes
+    * toggle force
+    * command to reparse just one (or more) bbfile(s)
+    * automatic check if reparsing is necessary (inotify?)
+    * frontend for bb file manipulation
+    * more shell-like features:
+        - shell lexer (shlex)
+        - output control, i.e. pipe output into grep, sort, etc.
+        - job control, i.e. bring running commands into background and foreground
+        - wildcards for commands, i.e. build *opie*
+    * start parsing in background right after startup
+    * print variable from package data
+    * ncurses interface
+    * read some initial commands from startup file (batch)
+
+MAYBE WORKING:
+   * poke doesn't work at all (outcommented atm.)
+
+PROBLEMS:
+    * force doesn't always work
+    * readline completion for commands with more than one parameters

It is most commonly used to build packages, as it can easily use its rudamentary inheritence to abstract common operations, such as fetching sources, unpacking them, patching them, compiling them, and so on.  It is the basis of the OpenEmbedded project, which is being used for OpenZaurus, Familiar, and a number of other Linux distributions.',

+Bitbake QA will hold Quality Assurance Resources:

+for any other user bitbake as well.

+doc/
+	This directory

+module_name/
+	QA modules doing the actual tests

+
+I hope to offer the following tests soon:
+
+source_checker - It will check if the sources can still be fetched
+		 and generates reports
+
+patch_checker  - It will check if the patches still applies
+
+doc_checker    - It will check if all variables have a documentation
+
+content_checker - It will check for common misusage in variables
+
+tinderbox_resources - It will contain resources to run a tinderbox server
+		      and client.
