1 Description

    l2x

    is a general-purpose LaTeX  converter. It  consists  of  a  parser
   written  in C, which then calls Tcl functions for each LaTeX  func-
   tion.  The Tcl functions return the translated value.

2 Installation

   The newest version of this package is available by anon. ftp. It is
   a  gzip'ed tar file. You must have the Tcl libraries installed, for
   example obtained by anonymous ftp. Edit the
    Makefile

   for the correct location of the Tcl library and include  files  and
   type

    make

3 Usage

   To translate the LaTeX  file
    input.tex

    using the translator

   foo.tcl

   :

     l2x foo.tcl < paper.tex

   The application
    lf

    is a filter that removes blank lines and, with the
    -b

    flag specified, initial blank space on lines. It is  intended  for
   nroff conversion. The application
    pgstrip

    removes extra blank lines from the beginning of a page and is  due
   to Jon Postel.  The script
    fix.sh

    processes an RFC or Internet Draft, including the necessary strip-
   ping of backspaces and the conversion of FORMFEED to real formfeeds
   (control-L).

   Currently, the following example translators are provided:

   l2html.tcl Convert input to a single HTML file.

   ms.tcl Convert to nroff/troff -ms macros.  Currently converts to  a
        format  suitable  for FAQs and READMEs (no page breaks or page
        numbers), but that is readily changed.

4 Limitations

   Currently, only a subset of LaTeX  commands is supported. Many  are
   easy  to  add,  but  the  following might require more work, albeit
   mostly limited to writing new Tcl functions:

        o  For conversion to HTML, math mode is supported  by  calling
         LaTeX and including the GIF image.

        o  The \newenvironment
          command is not supported.

        o  Table of contents, etc. are not supported in nroff.

5 Examples

   To convert nroff output to plain ASCII, without underscores, use

     l2x ms.tcl < foo.tex | nroff -ms | ul -tdumb > foo.txt
