=head1 DESCRIPTION

dh_installtex is a debhelper program that is responsible for
updating the ls-R databases, registering map files, new formats, 
and new hyphenation patterns with TeX.

Your package should depend on an appropriate version of tex-common so
that the update-* commands are available. (This program adds that
dependency to ${misc:Depends}.)

B<WARNING> This program does B<not> check for the actual existence of any 
input files in TEXMF trees. If you call it without any further specification
on which packages to work on (using C<-p> or C<-N>) it will add calls to
management functions to B<all> packages. In this case don't forget to 
add ${misc:Depends} to all packages' dependencies.

=head1 SIMPLE USAGE: Registering Files 

If you only install files into /usr/share/texmf, nothing has to be done,
tex-common will automatically detect changes and run mktexlsr.

=head1 COMPLEX USAGE: Registering fonts, hyphenation patterns and formats

If in addition, you have to install map files, hyphenation patterns for
additional languages, or format definitions you can use three
different methods to specify what should be installed:

1) B<Pre made config files:> These files can be specified with the
different I<type>file= options.
I<type> can be one of map, format and hyphen, and these files will be
installed into /var/lib/tex-common/I<configdir>/ for the respective type 
(fontmap-cfg for map files, hyphen-cnf for hyphenation patterns,
and fmtutil-cnf for format definitions).

Example:

        dh_installtex mapfile=foo.cfg formatfile=debian/bar.cnf

would install foo.cfg as /var/lib/tex-common/fontmap-cfg/texmf/foo.cfg, 
and debian/bar.cnf as /var/lib/tex-common/fmtutil-cnf/texmf/bar.cnf.


2) B<Directly on the cmd line:>
You can specify maps, formats, and hyphenations on the cmd line. The items
are stored in the respective config file 20package

Example:

        dh_installtex map=Map,foo.map hyphen=ngerman-x-2011-07-01,dehyphn-x-2011-07-01.tex,hyph-de-1996.pat.txt,lhm=2,rhm=2,synonym=ngerman-x-latest,exceptions=hyph-de-1996.hyp.txt

would install a file /var/lib/tex-common/fontmap-cfg/texmf/package.cfg containing the line

        Map foo.map

and a file /var/lib/tex-common/hyphen-cnf/texmf/package.cnf containing the lines

    name=ngerman-x-2011-07-01 file=dehyphn-x-2011-07-01.tex file_patterns=hyph-de-1996.pat.txt lefthyphenmin=2 righthyphenmin=2 synonym=ngerman-x-latest file_exceptions=hyph-de-1996.hyp.txt

3) B<Package files:>
You create a file debian/package.maps or debian/maps,
debian/package.hyphens or debian/hyphens, 
debian/package.formats or debian/formats. These files are
installed with the name of the package. Each of these
files will be installed into the first package dh_installtex
is told to act on. By default this is the first binary package in
debian/control, but if you use -p, -i, or -a flags, it will be the first
package specified by those flags.

Example:

        dh_installtex

would install a present debian/package.formats file as
/var/lib/tex-common/fmtutil-cnf/texmf/package.cnf.


=head2 Mixing the different variants

The command line items (Variant 2) are merged into the debian/package.maps 
(debian/package.hyphens, debian/package.formats) file. If you specify
an additional package.cfg/cnf (Variant 1) this will raise an error since
both files would be installed as package.cfg/cnf.

=head1 OPTIONS

=over 4

=item B<-n>, B<--noscripts>

Do not modify postinst/prerm scripts.

=item B<--flavor=>I<flavor>[,I<flavor>]

This option is used to select a different tree then the default
/usr/share/texmf, and to switch on additional options. The argument
specify a list from flavors to be selected.
At the moment you can select from the following list of flavors:
B<tree:texlive>,
B<map:config_for_active_maps>, B<map:config_for_all_maps>, 
B<format:add_one:I<formatname>>.

B<tree:texlive> will select the tree /usr/share/texlive/texmf-dist and
should only be used for files installed into this tree.

B<map:config_for_active_maps> will create a file I<config.bar> for each active
(i.e. uncommented) map in each of the cfg file generated by one of the
three methods described above. These files are installed in
/usr/share/texmf/dvips/config/.

If you select B<map:config_for_all_maps> the script will generate I<config.bar>
even for those map files which are present in a cfg file, but deactivated by a comment.

The file I<config.bar> is used when called by `dvips -Pbar ...'. Thus it
allows the activation of single map files even if they are not automatically
activated via the updmap(-sys) mechanism.

Default is I<not> to generate any config files.

B<format:add_one:I<formatname>> allows to add the generation of a specific
format without actually providing it (in a cnf file).  This is useful if a 
package adds hyphenation patterns to an existing formats.

B<format:no_links>:
Usually, for every format that is specified in a configuration file,
dh_installtex will create a symlink
/usr/bin/I<format> that points to the corresponding engine.  For
example, /usr/bin/latex would be created as a symlink to pdftex.  

The flavor B<format:no_links> inhibits this. If a link already
exists, dh_installtex will skip this format with an informational
message, even if this option is not given.

=head1 NOTES

"dh_installtex" adds a dependency relation onto tex-common to misc:Depends.

Note that this command is not idempotent. "dh_clean -k" should be called
between invocations of this command, unless using the B<-n> option.
Otherwise, it may cause multiple instances of the same text to be added
to maintainer scripts.

Please refer to the Debian TeX policy for details about fonts configuration
for TeX by Debian packages.
