Good idea... nice and clean...

I'm not following... This "low level font command" input file is user
specific...

I think the problem here has to do with Windows line breaks on non
Windows computers...

Was the attached file just as "hairy"...?

Yes, but first I would like to add a some python code to allow for a
"LaTeX preamble" input file for stuff like:

\DeclareMathAlphabet\mathscr{T1}{futs}{m}{it}

For custom mathscript or for custom macro definitions used within mpl
text..


User would also be able to load additional packages, like:

\usepackage[afrikaans,english]{babel} % Or other languages
\usepackage[iso,english]{isodate}     % For ISO style date format in
conjunction with the babel package
\usepackage{numprint}                 % For 123 456,789 number format
instead of 123,456.789


There would then be two optional LaTeX input files:

- a "LaTeX preamble" input file and/or
- a "low level font command" input file

(it would be difficult to combine them into one...)

Selectable with:

rcParams[latex.preamble.filename'] =3D 'MySimmulation.prbl
rcParams[latex.lowlevelfontcommand.filename] =3D 'MyPresentation.llfc'

Any suggestions for better rcParams names... (and extension... or is it
necessary, it could actually be anything... but a standard would be...
"nice")

Finally, with:

\usepackage{helvet}

in the "LaTeX preamble" input file,=20

rcParams['font.latex.package'] would become unnecessary... but IMHO
should be retained...
