+Project latex-tds
+-----------------
+
+Version: {revdate}
+
+How it has started
+~~~~~~~~~~~~~~~~~~
+The project started as I wanted to install the new LaTeX release 2005/12/01
+that was announced at 2006/04/27. However the files are not packed in
+TDS format, ready for unpacking in the destination directory. And
+the documentation files were not yet generated or the provided
+PDF files are lacking of basic features such as bookmarks or link support.
+Thus this project has started. I thought it could be finished during
+the afternoon at the day of the announcement ...
+
+Goals of the project
+~~~~~~~~~~~~~~~~~~~~
+* From the sources a TDS compliant tree is constructed and populated.
+ The zipped result is distributed.
+* All the documentation is generated from the sources. The PDF files
+ are user friendly and provide navigational support with bookmarks
+ and links.
+* The PDF files are post-processed to reduce the file size.
+
+Scope
+~~~~~
+I do not have the time to assemble a TeX distribution with
+thousands of packages. Therefore I restricted myself to the
+LaTeX base distribution and the required bundles.
+In the following I will use the term `module' for a package bundle.

+* +README+, +README.html+, +README.pdf+:
+ The README file in different formats.
+
+* +<module>.tds.zip+: The module distribution files,
+ see section `<<_module_list,Module list>>' above
+ for the available modules.
+
+* +source.tds.zip+: The sources, mainly the build script, configuration and
+ driver files, and patches.
+ Some of the used tools are not provided, see section
+ `<<_build_hints, Build Hints>>'.
+
+* +latex-tds.tds.zip+: The universe, the contents of all the ZIP files above,

+
+Installation Hints
+------------------
+
+Hopefully the result of this project helps you in the installation
+process. You get a TDS compliant tree just by unpacking.
+
+Example:
+----
+ cd /some/where/texmf
+ unzip latex-tds
+----
+or unzip's option +-d+:
+----
+ unzip latex-tds -d /some/where/texmf
+----
+
+Instead of the universe ZIP file single modules can be selected.
+
+Important to remember, point your unpack process right in
+the root directory of your TDS tree. The directory structure
+in the ZIP files start with the top-level directories:
+----
+ doc/latex/base/...
+ tex/latex/tools/...
+ source/...
+----
+Rationale: The root directory of a TDS tree can have different
+names, such as texmf-dist, texmf-local, ...
+
+Hints
+~~~~~
+--
+* Refresh the file name database.
+* Be aware that unpacking can insert and update files, but never
+ deletes obsolete ones. Remainders of previous releases can
+ cause trouble.
+* Depending on the module further installation steps can be
+ necessary, consult the module's own documentation.
+--
+
+Module base
+^^^^^^^^^^^
+ * The default +texsys.cfg+ that LaTeX provides is put
+ into +TDS:tex/latex/base+. It must be removed, if you need
+ a specialized version. Consult your TeX distribution
+ and +TDS:doc/latex/base/source2e.pdf+ (module ltdirchk).
+ Usually changes are not required for many TeX distributions
+ such as Unix (web2c), MikTeX, ...
+ * Formats need rebuilding (e.g., fmtutil).
+
+Module babel
+^^^^^^^^^^^^
+ * Most hyphenation patterns are not provided here. Usually you can
+ find them somewhere below {ctan}language/hyphenation/[CTAN:language/hyphenation/].
+ * Language configuration (+language.dat+), see the documentation of
+ your TeX distribution.
+ * Formats need rebuilding.
+
+Module psnfss
+^^^^^^^^^^^^^
+ * The map files need further configuring (e.g., updmap).
+
+Module graphics
+^^^^^^^^^^^^^^^
+ * Module graphics does not provide all driver files, because some are
+ developed independently (+pdftex.def+, ...).

+Design Principles
+-----------------
+
+* Compliance with the latest TDS specification.
+* No redundancy.
+* User friendly PDF files with navigational support:
+ - bookmarks
+ - links
+* Complete documentation. The documentation generation with
+ enhanced PDF files is the tricky part and should be saved
+ from the user.
+* Output format of generated documentation is PDF, see above.
+ Other formats such as DVI or PS are not generated and provided.
+* Documentation bundles are preferred to many partial documentation
+ files (e.g. +source2e.pdf+ or +ltnews.pdf+).
+* If several expansion stages of a documentation are available,
+ then just the most complete expansion stage should be used.
+* Files that do not fit in a program sub tree of TDS stay below
+ +TDS:source+ (e.g. +latexbug.el+ from latex/base). Then they do not
+ get lost at least.
+* Page layout: +a4paper+ with reduced vertical margins (exception: ltnews).
+ (This also decreases the page number usually.)
+* ...
+
+
+Remarks
+-------
+
+Base
+~~~~
+* +source2e.pdf+ is used instead of many single +lt*.pdf+ files.
+* +ltnews.pdf+ is introduced to avoid cluttering the doc directory
+ with many single sheet +ltnews*.pdf+ files.
+* Patch for +ltfssdcl.dtx+: Checksum fixed.
+* ...
+
+Tools
+~~~~~
+* Added: +tools.pdf+ as overview/contents/index file with links
+ and short descriptions of the single packages. (It uses
+ the data from +manifest.txt+).
+* ...
+
+Babel
+~~~~~
+* Babel's TeX files consists of three groups of files:
++
+ 1. Hyphenation pattern, see below.
+ 2. Generic files:
+ - +*.ldf+ (language definition files)
+ - +*.sty+ (from +bbcompat.dtx+, these are plain TeX files,
+ LaTeX user have the package babel)
+ - +babel.def+, +switch.def+
+ - +plain.def+
+ - +b*plain.tex+
+ - +esbst.tex+
+ 3. LaTeX files:
+ - +*.fd+
+ - +*enc.def+ (for package fontenc)
+ - +cp*.def+, +8859-8.def+, +si960.def+ (for package inputenc)
+ - +babel.sty+
+ - +romanidx.tex+
+ - +athnum.sty+, +grmath.sty+, +grsymb.sty+ (+greek.ins+)
+ - +heb*.sty+
+
++
+Full TDS compliance would use different format subtrees
+ for the generic and LaTeX files. However practice (TeX Live, teTeX,
+ VTeX, ...) put them in +generic+, mainly because of maintenance issues.
+ Also babel's +*.ins+ files specify +\usedir{tex/generic/babel}+.
+ There can be problems, if different TDS trees have different
+ babel versions installed and the same file can be found both
+ in generic and latex. The natural search strategy for TDS compliant
+ trees would be to look first in +tex/latex+ across the trees, then
+ in tex/generic. Thus it can happen to use files from the same
+ package, but different versions.
+ Therefore latex-tds put these files in the +generic+ subtree.
+--
+* Babel already contains +babel.pdf+ as documentation. It is a superset
+ of +user.pdf+. Thus I have dropped the latter one to avoid redundancy.
+ Also the name +babel.pdf+ is much more useful (texdoc).
+* ...
+--
+
+Knuth
+~~~~~
+* Current CTAN -> TDS mapping in use:
+ +CTAN:systems/knuth/dist+ -> +TDS:<toplevel>/knuth+
+* Unsure where to put trip/trap files. Currently they are
+ put in +TDS:source+, because the documentation files
+ (+tripman.pdf+, +trapman.pdf+) are in +TDS:doc+. They lists the
+ trip/trap files already.
+* Not covered is
+ {ctan}systems/knuth/dist/lib/[CTAN:systems/knuth/dist/lib/]
+ In TeX Live 2007/2008 the files are installed at different
+ locations:
++

+
+e-TeX
+~~~~~
+* Only the manual `etex_man' is covered by this module.
+
+
+Build Hints
+-----------
+
+The most important advice I can give: `Forget it'!
+The purpose of the source files are rather to show, what was
+done in which way.
+The +*.zip+ with TDS trees are the goal of the project, not the
+build process. Some remarks, if someone wants to build the
+modules himself:
+
+* TeX compiler: LuaTeX and pdfTeX (&ge; 1.30).
+* An up-to-date LaTeX installation, at least TeX Live 2012.
+* Additional packages can be necessary, e.g.
+ {ctan}language/armenian/armtex.zip[CTAN:language/armenian/armtex.zip]
+ is not part of TeX Live 2012.
+* Most of the PDF files are generated using lualatex and package
+ `fontspec' that uses the Latin Modern fonts as default. They
+ are available as OpenType fonts. LuaTeX generates with OpenType
+ fonts considerably smaller PDF files. Also PDF object stream
+ compression is used (PDF 1.5). Therefore the further
+ post-processing of PDF files are currently dropped.
+* (Outdated since 2011-07-01) PDF post-processing, I have used two steps:
++
+--
+ 1. First step:
+ a. I have written a tool that analyzes page stream contents and
+ optimizes them (removal of unnecessary color settings, minimize
+ translation operations, ...)
+ -> +pdfbox-rewrite.jar+.
+ b. For reading and writing the PDF file I have used PDFBox
+ -> +PDFBox-0.7.2.jar+ (http://pdfbox.apache.org/).
+ c. To get better results I patched some of the classes
+ of PDFBox (especially the write module)
+ -> +pdfbox-rewrite.jar+.
+ 2. The final conversion step was done by Multivalent, because
+ it makes a very good job in PDF compression:
+ -> +Multivalent20060102.jar+ (http://multivalent.sourceforge.net/)
+
+Multivalent and PDFBox are available, +pdfbox-rewrite.jar+, however,
+ is just a first prototype, not ripe for a release.
+ Therefore this step of post-processing is optional for the
+ project latex-tds. The build script looks for the library and
+ skips this steps automatically if necessary.
+ If you give the build script the option +--nopostprocess+,
+ then it will skip the postprocess steps (building is faster,
+ the pdf files a little larger).
+ Install the jar files in the directory +lib+ where
+ they are expected by the build script.
+--
+* Unix, Perl background is expected.
+* No support or documentation.
