Template-Plugin-Latex v$MODVERSION
------------------------------

The Template-Latex modules add LaTeX support for the Template Toolkit.

They allow you to create LaTeX documents using the full power of the
Template Toolkit.  The generated output can then be processed with
either 'pdflatex' or 'latex'.  If unresolved cross references,
bibliographic references or index definitions are found then 'bibtex'
or 'makeindex' will be run as appropriate and 'latex' or 'pdflatex'
re-run as necessary.  The output will be postprocessed with the
'dvips' and 'ps2pdf' programs if necessary to create PDF, DVI or
PostScript documents.

To use the Template-Latex module you will first need to install LaTeX on
your system and make sure the above programs are available.
