Package tetex: Information

teTeX is an implementation of TeX for Linux or UNIX systems.  TeX takes
a text file and a set of formatting commands as input and creates a
typesetter independent .dvi (DeVice Independent) file as output.  Usually,
TeX is used in conjunction with a higher level formatting package like
LaTeX or PlainTeX, since TeX by itself is not very user-friendly.

Install teTeX if you want to use the TeX text formatting system.  If you
are installing teTeX, you would probably also need to install tetex-afm (a
PostScript(TM) font converter for TeX), tetex-dvilj (for converting .dvi
files to HP PCL format for printing on HP and HP compatible printers),
tetex-dvips (for converting .dvi files to PostScript format for printing
on PostScript printers), tetex-latex (a higher level formatting package
which provides an easier-to-use interface for TeX) and tetex-xdvi (for
previewing .dvi files in X).  Unless you're an expert at using TeX,
you'll also want to install the tetex-doc package, which includes the
documentation for TeX.
