On all computers of the faculty the LaTeX distriburion Tex Live is installed. In addition, a number of further LaTeX classes are availabale, which are described here.
The class math-brief can be used to write letters with the official faculty letter head. An example letter describing all options can be found on each computer at the path
/usr/local/share/texmf/tex/latex/math-brief/math-brief.tex
The text of this letter can be viewed here. You can mark the text in the browser, copy it into an editor, and save it as .tex file.
There ist also a class math-neutral for a letter without address, just with the university logo and possibly the sender address. An example of its usage can be found here and at the path
/usr/local/share/texmf/tex/latex/math-brief/math-neutral.tex
To produce announcements and posters the class math-aushang can be used. An example is here and at the path
/usr/local/share/texmf/tex/latex/math-brief/math-aushang.tex
The Euro sign can be made available with the package marvosym. If you put
\usepackage{marvosym}
into the header of your LaTeX file, you can enter the Euro sign as \EUR.
All computers of the faculty use UTF-8 font encoding by default. UTF-8 encoded LaTeX source files containing non-ASCII characters like Umlaute can be processed directly with LaTeX, if the following option is added to the header:
\usepackage[utf8]{inputenc}
This avoids having to write \"a for ä, etc. In a similar way, support for files encoded in ISO latin1 or othe encodings can be added.
The support for other languages is described here.
