=head1 NAME
sty2dtx -- Converts a LaTeX .sty file to a documented .dtx file

=head1 DESCRIPTION
Converts a .sty file (LaTeX package) to .dtx format (documented LaTeX source),
by surrounding macro definitions with 'macro' and 'macrocode' environments.
The macro name is automatically inserted as an argument to the 'macro'
environemnt.
Code lines outside macro definitions are wrapped only in 'macrocode'
environments. Empty lines are removed.
The script is not thought to be fool proof and 100% accurate but rather
as a good start to convert undocumented style files to .dtx files.
=head2 Basic Usage
perl sty2dtx.pl infile [infile ...] outfile
or
perl sty2dtx.pl < file.sty > file.dtx
=head2 Supported Definitions
The following macro definitions are detected when they are at the start of a
line (can be prefixed by \global, \long, \protected and/or \outer):
\def \edef \gdef \xdef
\newcommand{\name} \newcommand*{\name}
\newcommand\name \newcommand*\name
\renewcommand{\name} \renewcommand*{\name}
\renewcommand\name \renewcommand*\name
\providecommand{\name} \providecommand*{\name}
\providecommand\name \providecommand*\name
\@namedef{\name} \@namedef\name
The following environment definitions are detected when they are at the start
of a line:
\newenvironment{name} \renewenvironemnt{name} \provideenvironment{name}
The macro and environment definition must either end at the same line or with
a 'C<}>' on its own on a line.
=head1 USAGE
sty2dtx [<options>] [--<VAR>=<VALUE> ...] [--] [<infile(s)>] [<outfile>]
=head2 Files
=over 2
=item *
can be 'C<->' for STDIN or STDOUT, which is the default if no files are given
=item *
multiple input files are merged to one output file
=back
=head2 Variables
Variables can be defined using
--<VAR>=<VALUE>
or
--<VAR> <VALUE>
and will be used for substitutions in the template file.
=head3 Common variables:
author, email, maintainer, year (for copyright),
version, date, description (of package/class),
type (either 'package' default or 'class'),
filebase (automatically set from output or input file name),
=head2 Options
=over 8
=item B<-h> S< >
Print this help text
=item B<-H> S< >
Print extended help
=item B<-V> S< >
Print version and copyright
=item B<-v> S< >
Be verbose
=item B<-o> F<output> S< >
Use given file as output
=item B<-O> S< >
Overwrite already existing output file(s)
=item B<-B> S< >
Use basename of single input file for output file
=item B<-I> S< >
Also create .ins (install) file
=item B<-c> S< >
Only use code section (like v1.0)
=item B<-r> S< >
Remove existing 'macro', 'macrocode', etc. environments.
=item B<-R> S< >
Do not remove existing 'macro', 'macrocode', etc. environments.
=item B<-i> F<ins-file> S< >
Create .ins file with given name
=item B<-t> F<template> S< >
Use this file as template instead of the default one
=item B<-T> F<template> S< >
Use this file as template for the .ins file
=item B<-e> F<file> S< >
Export default .dtx template to file and exit
=item B<-E> F<file> S< >
Export default .ins template to file and exit
=item B<-D> S< >
Use current date as file date
=item B<-F> F<file> S< >
Read more options and variables from file.
=item B<-N> S< >
Do not read default config file; must be the first option
=back
=head2 Config files
A default config file either named 'sty2dtx.cfg' or '.sty2dtx.cfg' is searched
in the current directory, the users home directory and the directory of this
script, in this order. The first one found is loaded. If none is found the
'texmf' tree is searched for a 'sty2dtx.cfg' config file. As with -F files the
config file should contain one option or variable per line.
Lines starting with 'C<%>' or 'C<#>' are ignored.
=head1 Examples
Produce 'file.dtx' from 'file.sty':
sty2dtx.pl < file.sty > file.dtx
or
sty2dtx.pl file.sty file.dtx
or
sty2dtx.pl -B file.sty
Produce 'file.dtx' and 'file.ins' from 'file.sty':
sty2dtx.pl -I file.sty file.dtx
or
sty2dtx.pl file.sty -i file.sty file.dtx
or
sty2dtx.pl -IB file.sty
Set custom variable values:
sty2dtx.pl --author Me --email me@there.com mypkg.sty mypkg.dtx
Produce DTX file for a class:
sty2dtx.pl --type class mycls.sty mycls.dtx

# The templates for the DTX file and INS file
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
# Adepted from the skeleton file provided by the 'dtxtut' (DTX tuturial).
# The '<+var+>' format was choosen because it is used by the latex suite for Vim.
# Therfore all variables which are not expanded are easily accessible to the
# user using a certain feature in the latex suite.
#
# Perl modules like 'Template' were not used to support minimal Perl installation
# for typical LaTeX installations.
