[l2h] LaTeXCleaner

[Hassan Monzavi]

# LaTeX and HTML are both mark up languages, but also different due to their
# interpritation by their browsers and their presentation.  Some ideas in one
# language is critical and not very important in the other.  In addition, the 
# latex2html convertor is in a development stage and still is not perfect.  So I
# think it's not a bad idea to clean our tex files before passing them to
# latex2html.
# The following is a script based on sed editor and helps to do some clean up. 
# I am not an expert in Latex, not very good in sed and just work with
# latex2html for less than one week.  So, please feel free to modify the code a
# share your ideas and experiences to improve this script and make it smarter.
# If you are interested you can save whole thing as say "LaTeXCleaner" and then 
# use it like:
# cat <tex input file> | sed -f LaTeXCleaner > <tex out put file>
# <tex input file> stands for your original tex file and
# <tex out file> stands for the name you choose for cleaned tex file.

# This part will replace all slide environments with section environment, by
# eliminating of the \end{slide}s, \begin{slide}s and \begin{center} after them. 
# It also tries to make a title for the section. Still way to go!

# may be a slightly different size (say smaller) for caption in Tables and 
# Figures.
