=head1 NAME

bundledoc - bundle all the files needed by a LaTeX document

=head1 SYNOPSIS

bundledoc
[B<--version>]
[B<--help>]
[B<-->[B<no>]B<verbose>]
[B<--texfile>=I<file.tex>]
[B<--directory>=I<directory>]
[B<-->[B<no>]B<localonly>]
[B<--exclude>=I<string>]
[B<--include>=I<filespec>]
[B<--manifest>=I<file>]
[B<-->B<listdeps>=[yes|no|only|rel]...]
[B<-->[B<no>]B<keepdirs>]
[B<--config>=I<file.cfg>]
I<file.dep>

=head1 DESCRIPTION

B<bundledoc> is a post-processor for the B<snapshot> package that
bundles together all the classes, packages, and files needed to build
a given LaTeX document.  It reads the F<.dep> file that B<snapshot>
produces, finds each of the files mentioned therein, and packages them
into a single archive file (e.g., a F<.tar.gz> file), suitable for
moving across systems, transmitting to a colleague, etc.

As the simplest example possible, consider a LaTeX file called, say,
F<hello.tex>:

\RequirePackage{snapshot}       % Needed by bundledoc
    \documentclass[11pt]{article}

\begin{document}
    Hello, world!
    \end{document}

The C<\RequirePackage{snapshot}> causes a F<hello.dep> file to be produced.
When B<bundledoc> is then given C<hello.dep> as an argument, it locates the
dependent files -- F<snapshot.sty>, F<article.cls>, and F<size11.clo> --
and bundles them into a single archive file, along with F<hello.tex> and a
F<MANIFEST> file (described in L<"OPTIONS">, below).

=head1 OPTIONS

In the following descriptions, I<somefile> refers to the name of your
main LaTeX document (no extension).

B<bundledoc> requires the name of the dependency file produced by
B<snapshot>, normally I<somefile>F<.dep>).  (For convenience, the file
can be specified without its F<.dep> extension.)  The following
options may also be given:

=over 4

=item B<--version>

Output the B<bundledoc> script's version number.  This overrides all
of the remaining options.

=item B<--help>

Give a brief usage message.  This overrides all of the remaining options.

=item B<-->[B<no>]B<verbose>                    (default: C<noverbose>)

B<bundledoc> normally does not output anything except error messages.
With C<--verbose>, it outputs copious status messages.

=item B<--texfile>=I<main .tex file>            (default: I<somefile>F<.tex>)

B<snapshot>'s dependency file does not list the main LaTeX file (the
one that gets passed to B<latex>).  In order for B<bundledoc> to find
and bundle that file, B<bundledoc> assumes it has the same name as the
B<snapshot> dependency file but with a F<.tex> extension.  If this is
not the case, then use C<--texfile> to specify the correct filename.

=item B<--directory>=I<archive directory>       (default: I<somefile>)

When B<bundledoc> creates an archive (e.g., a F<.tar> or F<.zip> file)
containing the document's files, it puts all of them in a directory to
avoid cluttering the current directory with files.  If the given
dependency file is called I<somefile>F<.dep> then the resulting
archive will, by default, store all the dependent files in a
I<somefile> directory.  To change the directory name use the
C<--directory> option.

=item B<-->[B<no>]B<localonly>                  (default: C<nolocalonly>)

Although B<bundledoc> normally archives all of the files named in the
F<.dep> file, the C<--localonly> option tells B<bundledoc> to exclude
all files located in a directory other than the F<.tex> file's
directory or one of its subdirectories.

=item B<--exclude>=I<string>                    (default: I<none>)

While C<--localonly> causes files outside of the F<.tex> file's
directory tree to be omitted from the archive, C<--exclude> provides
finer-grained control over files to omit from the archive.  The
C<--exclude> option, which can be specified repeatedly on the command
line, causes all files whose name contains I<string> to be omitted
from the archive.

=item B<--include>=I<filespec>                  (default: I<none>)

The C<--include> option, which can be specified repeatedly on the
command line, instructs B<bundledoc> to include in the archive all of
the files matching I<filespec>, even if they're not referenced in the
F<.dep> file.

=item B<--manifest>=I<manifest file>            (default: F<MANIFEST>)

In addition to the dependent files, B<bundledoc> includes in the
archive file one extra file called, by default, ``F<MANIFEST>''.
F<MANIFEST> is a text file that lists the original filenames of all
the dependencies.  To change the filename from ``F<MANIFEST>'' to
something else, use the C<--manifest> option.  As a special case,
C<--manifest=""> tells B<bundledoc> not to include a manifest file at
all.

=item B<--listdeps>=[yes|no|only|rel]...]       (default: C<no>)

C<--listdeps> accepts one or more of C<yes>, C<no>, C<only>, or C<rel>
as a comma-separated list.  As long as C<no> does not appear in this
list, B<bundledoc> outputs all of the main LaTeX file's dependencies.
If the list contains C<rel>, then B<bundledoc> outputs the list of
dependencies with relative pathnames.  If the list contains C<only>,
then B<bundledoc> exits after displaying the list, without producing
an archive.

=item B<-->[B<no>]B<keepdirs>                   (default: C<nokeepdirs>)

Normally, the archive file that B<bundledoc> produces contains a
single directory -- and subdirectories, if the document refers
explicitly to them -- in which all the dependent files lie.  If
C<--keepdirs> is specified, all the dependent files are stored with
their original pathnames.  For example, if F<somefile.tex> depends on
F<figures/somefigure.eps>, F<article.cls>, and F<snapshot.sty>, then
the I<somefile> archive will normally contain the following files:

=over 4

=item *

F<somefile/somefile.tex>

=item *

F<somefile/figures/somefigure.eps>

=item *

F<somefile/article.cls>

=item *

F<somefile/snapshot.sty>

=item *

F<somefile/MANIFEST>

=back

However, C<--keepdirs> will cause the I<somefile> archive to contain
the following sorts of filenames instead:

=over 4

=item *

F<home/me/mydocs/somefile.tex>

=item *

F<home/me/mydocs/figures/somefigure.eps>

=item *

F<usr/share/texmf/tex/latex/base/article.cls>

=item *

F<usr/share/texmf/tex/latex/snapshot/snapshot.sty>

=back

C<--directory> is not used when C<--keepdirs> is in effect.  In
addition, no manifest file is written to the archive file as it
contains redundant information.

=item B<--config>=I<configuration file>         (default: E<lt>noneE<gt>)

The C<--config> option is used to point B<bundledoc> to the
appropriate configuration (F<.cfg>) file for your TeX distribution and
operating system.  B<bundledoc> comes with a few configuration files
and it's easy to write more.  See L<"CONFIGURATION FILES"> (below) for
a description of the configuration file format.  For convenience, the
file can be specified without its F<.cfg> extension.

=back

=head1 CONFIGURATION FILES

=head2 Format

Configuration files follow a fairly simple format.  Lines beginning with
C<#> are comments.  Blank lines are ignored.  All other lines are of the
form:

variable: value

The current version of B<bundledoc> recognizes the following variables:

=over 4

=item B<bundle>

The command to use to bundle a set of files into a single archive file

=item B<sink>

The affix to a command to discard its output

=item B<find>

The command to find a file within the TeX tree(s).

=back

Values that are too long for one line can be split across multiple lines
by using C<\> as the line-continuation symbol.

There are two environment variables that B<bundledoc> makes available
for use by configuration-file commands: C<BDBASE>, which is set to
I<somefile> (as in L<"OPTIONS">), and C<BDINPUTS>, which is set to a
space-separated list of files that a command is to operate upon.  That
is, when the command associated with C<bundle> is running, C<BDINPUTS>
contains the list of all the files that are to be archived.  In
contrast, when the command associated with C<find> is running,
C<BDINPUTS> contains the name of the file to search for.

=head2 Examples

The following configuration file parallels B<bundledoc>'s default
values of the various configuration-file variables, which represents a
kpathsea-based TeX distribution running on a generic Unix system,
which doesn't necessarily have any of the GNU tools, such as B<gzip>
or GNU B<tar>:

# "Default" configuration file
    # By Scott Pakin <scott+bdoc@pakin.org>

bundle: (tar -cvf - $BDINPUTS | compress > $BDBASE.tar.Z)
    sink:   > /dev/null 2>&1
    find:   kpsewhich -progname=latex $BDINPUTS

The parentheses in the C<bundle:> line tell the Unix shell to run the
command in a subshell.  This is to make the C<sink:> affix work
properly (i.e., so there aren't two C<E<gt>>'s in the same command).

Notice how the commands treat C<BDBASE> and C<BDINPUTS> like any other
environment variables in a Unix shell, using C<$> to take their value.
Other operating systems use different conventions for referring to
environment variables.  For instance, a configuration file for a
Windows-based TeX distribution would use C<%BDBASE%> and C<%BDINPUTS%>
instead.

The value for C<sink:> is specific to an operating system.  The value
for C<find:> is specific to a TeX distribution.  C<bundle:> is where
the most opportunity for customization lies.  You can use C<bundle:>
to specify your favorite archive format.  For example, you can produce
a shar file on Unix with something like:

bundle: (shar --archive-name="$BDBASE" $BDINPUTS > $BDBASE.sh)

or a CAB file on Microsoft Windows with something like:

bundle: cabarc -r -p N %BDBASE%.cab %BDINPUTS%

=head1 EXAMPLES

Assume that F<myfile.dep> was produced from F<myfile.tex> by following
the instructions in L<the Description section|/"DESCRIPTION">.  The
following command produces a F<.zip> file with the MikTeX TeX
distribution running on Microsoft Windows:

bundledoc --config=miktex.cfg myfile.dep

This can be abbreviated to

bundledoc --config=miktex myfile

The following builds a F<.tar.gz> archive with the TeX Live
distribution running on a Unix-like operating system.  B<bundledoc>
will produce verbose output describing its operations.  All files not
in the same directory tree as F<myfile.tex> and all files containing
".fd" or ".sty" in their names are omitted.  However, all F<.bib>
files in the current directory will be included in the archive even
though none of them are referenced by F<myfile.dep>.  Finally, no
F<MANIFEST> file will be produced.

bundledoc --config=texlive-unix.cfg --verbose --localonly \
      --exclude=.fd --exclude=.cfg --include="*.bib" --manifest="" \
      myfile.dep

=head1 FILES

The user must have previously installed F<snapshot.sty> and used it to
produce a dependency file for his document.  Besides that, the set of
external files needed by B<bundledoc> is system-specific and depends on the
configuration file used.  (See L<"CONFIGURATION FILES">, above.)

B<bundledoc> currently comes with two configuration files:

=over 4

=item F<texlive-unix.cfg>

Configuration file for TeX Live installations on Unix or Linux.  TeX
Live is a kpathsea-based TeX distribution that runs on various flavors
of Unix and Microsoft Windows.  F<texlive-unix.cfg> assumes you have
B<gzip> and uses it to produce a F<.tar.gz> archive file.  The
configuration file has B<bundledoc> use B<kpsewhich> to find LaTeX
files.

=item F<miktex.cfg>

Configuration file for MikTeX installations.  MikTeX is a popular TeX
distribution for Microsoft Windows.  F<miktex.cfg> assumes you have
B<zip> and uses it to produce a F<.zip> archive file.  The
configuration file now has B<bundledoc> use B<kpsewhich> to find LaTeX
files; older version of MikTeX required the rather nonstandard
B<initexmf> for this purpose.

=item F<texlive-unix-arlatex.cfg>

This is a variant of F<texlive-unix.cfg> that uses B<arlatex> instead
of B<gzip> to archive files.  B<arlatex> is a script included in the
B<bundledoc> distribution that generates a self-extracting F<.tex>
file based on LaTeX's C<filecontents> environment.

=back

=head1 NOTES

=head2 Including and excluding files

The C<--localonly>, C<--exclude>, and C<--include> options provide
control over the archive's contents.  C<--exclude> and C<--include>
can be specified repeatedly on the command line.  The order in which
these options are specified is immaterial; B<bundledoc> processes file
inclusions and exclusions in the following order:

=over 4

=item 1.

All files referenced by the F<.dep> file are added to the list of
files to archive.

=item 2.

If C<--localonly> is specified, all files not found in the F<.tex>
file's directory are removed from the list.

=item 3.

For each C<--exclude> string specified, all files containing that
string are removed from the list.

=item 4.

For each C<--include> file specification, the set of files designated
by its expansion are added to the list.

=back

=head2 Issues When Running Under Microsoft Windows

First, because B<bundledoc> is a Perl script, you should do one of the
following to run it under Windows:

=over 4

=item *

C<perl bundledoc>

=item *

Rename F<bundledoc> to F<bundledoc.pl> and run C<bundledoc.pl>.  (This
is assuming you have a file association set up for F<.pl>.)

=item *

Run the B<pl2bat> script (if you have it) to convert F<bundledoc> to
F<bundledoc.bat>, then run C<bundledoc>.

=back

Second, Windows uses a multi-rooted filesystem (i.e., multiple drive
letters).  I wouldn't be surprised if bad things were to happen if the
files to be bundled are scattered across drives.  In addition, Windows
supports ``UNC'' filenames, which have no drive letter at all, just a
machine and share name.  UNC filenames are also untested waters for
B<bundledoc>.  Be careful!

=head2 Testing Status

I have tested B<bundledoc> only with Perl v5.6.0 and later and only on
the following platforms:

=over 4

=item *

Linux + TeX Live

=item *

Linux + teTeX

=item *

Windows NT + MiKTeX

=item *

Solaris + ??? (something kpathsea-based)

=back

It is my hope that B<bundledoc> works on many more platforms than
those.  I tried to make the program itself fairly independent of the
operating system; only the configuration files should have to change
to run B<bundledoc> on a different system.

=head2 Future Work

I'd like B<bundledoc> to work on as wide a variety of TeX
distributions as possible.  If your platform is significantly
different from the ones listed in L<"Testing Status"> (e.g., if you're
running S<OS X>) and you need to create a substantially different
configuration file from F<texlive-unix.cfg> and F<miktex.cfg>, please
send it to me at the address listed in L<"AUTHOR"> so I can include it
in a future version of B<bundledoc>.  (I make no promises, though).

Once B<bundledoc> works on all the major operating systems and TeX
distributions it would be really convenient if I could get
B<bundledoc> to detect the platform it's running on and automatically
select an appropriate configuration file.

Finally, it would be handy for B<bundledoc> to include fonts in the
archive file.  At a minimum, it should include F<.tfm> files, but it
would be even better if it included F<.mf>, F<.pfb>, F<.ttf>, and
other common font formats, as well.

=head2 Acknowledgments

Thanks to Fabien Vignes-Tourneret for suggesting what became the
C<--localonly> option and for a discussion that led to the
C<--exclude> and C<--include> options; to Marius Kleiner for updating
B<bundledoc> to properly handle document subdirectories; and to Frank
Mittelbach for suggesting using Kpathsea to help find F<.cfg> files
and to automatically append F<.cfg> and F<.dep> extensions if
necessary.
