# Generate docs from latex package/class...
#
# 	- keep lines starting with \def\<module-name>@[A-Z]\+
# 	- keep lines starting with '%%'
# 	- %%%%% Text -> \subsection(Text)
# 	- %%%% Text -> \section(Text)
# 	- %% >> code -> \begin{verbatim}code\end{verbatim}
#
# NOTE: the idea of keeping latex docs in a latex file is far similar 
# 		than all the stuff crammed into .dtx, at least for my needs:
# 			- keep the code readable
# 			- keep the docs readable
# 		in both the repo and in installed form.
# NOTE: this is evolving as need arises, when this gets too complicated 
# 		we'll split it out into it's own script.
