+__DATA__
+
+=head1 NAME
+
+mkjobtexmf -- Generate a texmf tree for a particular job
+
+=head1 SYNOPSIS
+
+The progam B<mkjobtexmf> runs a program and tries to
+find the used file names. Two methods are available,
+option C<-recorder> of TeX (Web2C) or the program B<strace>.
+
+Then it generates a directory with a texmf tree. It checks
+the found files and tries sort them in this texmf tree.
+
+It can be used for archiving purposes or to speed up
+following TeX runs.
+
+ mkjobtexmf [options]
+
+This runs TeX that can be configured by options.
+Both methods for getting the used file names are available.
+
+ mkjobtexmf [options] -- <cmd> [args]
+
+The latter form runs program I<cmd> with arguments I<args>
+instead of TeX. As method only program B<strace> is available.
+
+Options:
+
+ --jobname <name> Name of the job (mandatory).
+ Usually this is the TeX file
+ without extension
+ --texname <file> Input file for TeX. Default is the
+ job name with extension '.tex'
+ --texopt <option> Option for TeX run
+ --destdir <directory> Destination directory,
+ default is `<jobname>.mjt'
+ --output Add also output files
+ --strace Use strace instead of TeX's
+ option -recorder
+ --copy Copy files instead of creating
+ symbol links
+ --flat Junk paths, do not make directories
+ inside the destination directory
+ --cmd-tex <cmd> Command for the TeX compiler
+ --cmd-kpsewhich <cmd> Command for kpsewhich
+ --cmd-texhash <cmd> Command for texhash
+ --cmd-strace <cmd> Command for strace
+ --verbose Verbose output
+ --help Brief help message
+ --man Full documentation
+
+=head1 DESCRIPTION
+
+=head2 Running the program
+
+First B<mkjobtexmf> runs a program, usually TeX. The TeX compiler
+is configured by option B<--cmd-tex>. Option B<--texname> can
+be used, if the file name extension differs from F<.tex>:
+
+ mkjobtexmf --jobname foo --texname foo.ltx
+
+Even more complicate cases are possible:
+
+ mkjobtexmf --jobname foo --texname '\def\abc{...}\input{foo}'
+
+If another program than TeX should be used (dvips, ...),
+then this program can be given after C<-->:
+
+ mkjobtexmf --jobname foo -- dvips foo
+
+=head2 File recording
+
+Two methods are available to get the used file names:
+
+=over
+
+=item Recorder of TeX
+
+Some TeX distributions (e.g. Web2C) support the option B<-recorder>
+for its TeX compilers. Then the TeX compiler generates a file with
+extension F<.fls> that records the used input and output files.
+
+=item Program strace
+
+This program traces system calls and signals. It is used here
+to log the used files.
+
+=back
+
+=head2 Analyze and link/copy found files
+
+The result directory F<I<jobname>.mjt> is generated. Inside the
+result TEXMF tree is created. Each found file is compared against
+a list of paths of TEXMF trees. If a match is found, the file is
+linked/copied into the TEXMF tree. The list of paths is generated by
+program B<kpsewhich>.
+
+If the file cannot be mapped to a TEXMF tree and the file is
+a relative file name, then it is directly linked/copied into the
+result directory F<I<jobname>.mjt>. Absolute file names
+are not supported and neither paths with links to parent directories.
+
+Symbolic links are created by default. The files are copied
+if option --copy is given or symbolic linking is not available.
+
+=head1 OPTIONS
+
+=over
+
+=item B<--jobname>=I<jobname>
+
+It is the name of the job. `<jobname>.tex' serves as default for
+the TeX file and <jobname> is used for naming various directories
+and files. See section L</FILES>.
+
+=item B<--texname>=I<name>
+
+The name of the TeX input file, if it differs from <jobname>.tex.
+
+=item B<--texopt>=I<opt>
+
+Additional option for the TeX compiler, examples are --ini or
+--shell-escape. This option can be given more than once.
+
+=item B<--destdir>=I<directory>
+
+Specifies the name of the destination directory where the result
+is collected. As default a directory is generated in the current
+directory with the job name and extension `.mjt'.
+
+=item B<--output>
+
+Also add output files.
+
+=item B<--strace>
+
+Use method with program B<strace>, see L<"DESCRIPTION">.
+
+=item B<--copy>
+
+Files are copied instead of creating symbolic links.
+
+=item B<--flat>
+
+Files are linked or copied without path elements.
+The destination directory will contain a flat list of
+files or links without directory.
+
+The files `ls-R' and `aliases' are ignored.
+
+=item B<--cmd-tex>=I<cmd>
+
+Command for the TeX compiler. Default is pdflatex.
+
+=item B<--cmd-kpsewhich>=I<cmd>
+
+Command for kpsewhich.
+
+=item B<--cmd-texhash>=I<cmd>
+
+Command for updating the file name database of the generated
+texmf tree. Default is texmf.
+
+=item B<--cmd-strace>=I<cmd>
+
+Command for strace.
+
+=item B<--verbose>
+
+Verbose messages.
+
+=item B<--help>
+
+Display help screen.

+
+=head1 EXAMPLES
+
+TeX file F<test.tex> using TeX's recorder method:
+
+ mkjobtexmf --jobname test
+
+TeX file F<test.tex> using LaTeX:
+
+ mkjobtexmf --jobname test --cmd-tex latex
+
+Format generation:
+
+ mkjobtexmf --jobname test --texopt -ini --texname pdflatex.ini
+
+Example, how the new texmf tree (Linux/bash) can be used:
+
+ TEXMF=!!test.mjt/texmf pdflatex test
+
+Example for generating a zip archive (Linux/bash):
+
+ (cd test.mjt && zip -9r ../test .)
+
+Example for generating a tar archive:
+
+ tar cjhvf test.tar.bz2 -C test.mjt .
+
+=head1 UNSOLVED ISSUES, CAVEATS, TODOS
+
+=over
+
+=item Experimental software
+
+Options, defaults, how the program works might change in
+future versions.
+
+=item F<texmf.cnf>
+
+Currently the method with B<strace> records this files.
+TeX's recorder does not. Useful are F<texmf.cnf> files for
+variable settings. Because we have just one TEXMF tree,
+the path sections should probably rewritten.
+
+=item Settings in environment variables
+
+They are not stored at all.
+
+=item Collisions
+
+The program uses one destination directory and at most
+one TEXMF tree for the result. However, the source files
+can come from different directories and TEXMF trees.
+Therefore name collisions are possible.
+
+The program follows the strategy not to delete files
+in the destination directory. That allows to collect files
+from differnt runs. Thus collisions are resolved
+in the manner that the first entry that is made in
+the destination directory wins.
+
+=item Configuration file
+
+It would save the user from retyping the same options again and again.
+
+=item Uncomplete recording
+
+Bugs in TeX's file recording might result in incomplete
+file recording (e.g. pdfTeX 1.40.3 does not record .pfb and
+.pk files).
+
+=item ...
+
+=back
+
+=head1 FILES
+
+=over
+
+=item F<E<lt>jobnameE<gt>.mjt/>
+
+Directory where the resulting texmf tree and symbol links
+are stored. It can be changed by option --destdir.
+
+=item F<E<lt>jobnameE<gt>.fls>
+
+Name of TeX's recorder file.
+
+=item F<E<lt>jobnameE<gt>.strace>
+
+Log file where the result of B<strace> is stored.
