# pod2latex, version 1.1
# by Taro Kawagish (kawagish@imslab.co.jp),  Jan 11, 1995.
#
# pod2latex filters Perl pod documents to LaTeX documents.
#
# What pod2latex does:
# 1. Pod file 'perl_doc_entry.pod' is filtered to 'perl_doc_entry.tex'.
# 2. Indented paragraphs are translated into
#    '\begin{verbatim} ... \end{verbatim}'.
# 3. '=head1 heading' command is translated into '\section{heading}'
# 4. '=head2 heading' command is translated into '\subsection*{heading}'
# 5. '=over N' command is translated into
#        '\begin{itemize}'	if following =item starts with *,
#        '\begin{enumerate}'	if following =item starts with 1.,
#        '\begin{description}'	if else.
#      (indentation level N is ignored.)
# 6. '=item * heading' command is translated into '\item heading',
#    '=item 1. heading' command is translated into '\item heading',
#    '=item heading' command(other) is translated into '\item[heading]'.
# 7. '=back' command is translated into
#        '\end{itemize}'	if started with '\begin{itemize}',
#        '\end{enumerate}'	if started with '\begin{enumerate}',
#        '\end{description}'	if started with '\begin{description}'.
# 8. other paragraphs are translated into strings with TeX special characters
#    escaped.
# 9. In heading text, and other paragraphs, the following translation of pod
#    quotes are done, and then TeX special characters are escaped after that.
#      I<text> to {\em text\/},
#      B<text> to {\bf text},
#      S<text> to text1,
#        where text1 is a string with blank characters replaced with ~,
#      C<text> to {\tt text2},
#        where text2 is a string with TeX special characters escaped to
#        obtain a literal printout,
#      E<text> (HTML escape) to TeX escaped string,
#      L<text> to referencing string as is done by pod2man,
#      F<file> to {\em file\/},
#      Z<> to a null string,
# 10. those headings are indexed:
#       '=head1 heading'   =>  \section{heading}\index{heading}
#       '=head2 heading'   =>  \subsection*{heading}\index{heading}
#                 only when heading does not match frequent patterns such as
#                 DESCRIPTION, DIAGNOSTICS,...
#       '=item heading'   =>  \item{heading}\index{heading}
#
# Usage:
#     pod2latex perl_doc_entry.pod
# this will write to a file 'perl_doc_entry.tex'.
#
# To LaTeX:
# The following commands need to be defined in the preamble of the LaTeX
# document:
# \def\C++{{\rm C\kern-.05em\raise.3ex\hbox{\footnotesize ++}}}
# \def\underscore{\leavevmode\kern.04em\vbox{\hrule width 0.4em height 0.3pt}}
# and \parindent should be set zero:
# \setlength{\parindent}{0pt}
#
# Note:
# This script was written modifing pod2man.
#
# Bug:
# If HTML escapes E<text> other than E<amp>,E<lt>,E<gt>,E<quot> are used
# in C<>, translation will produce wrong character strings.
# Translation of HTML escapes of various European accents might be wrong.
