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
Install teTeX if you want to use the TeX text formatting system. If
you are installing teTeX, you will 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.
