A little bit, although sadly I had few chances to actually use LaTeX since I left the University. So I enjoy this even more :-) > So maybe you can help me with this. > > I would like to > > 1.

I put the answer to both questions into a minimal example: \documentclass{minimal} % should work with any document class \IfFileExists{mnsymbol.sty}{% \usepackage{mnsymbol} }{% \PackageWarning{orgmode}{mnsymbol.sty not found, using fall-back-replacements} } \providecommand*{\mnstar}{*} % provide alternative in case command not available \begin{document} \mnstar \end{document} Some notes: - IfFileExists finds the sty file anywhere in the tex load path (you can verify this with "kpsewhich FILE" on the commandline). These commands are explained in the LaTeX Class writing guide: texdoc clsguide - \providecommand* is the same as \providecommand, but saves a tiny bit of memory as no arguments are allowed that contain multiple paragraphs (not making the *-variant the default for \providecommand and \newcommand is in my opinion clearly a design flaw of LaTeX).
