 ctioga2 is a plotting program in the spirit of gnuplot. It can be
 used either directly on command-line or writing command files (or a
 mix of both). It produces publication-quality PDF files. It is based
 on the Tioga plotting library.

 ctioga2 is a full rewrite of ctioga and is meant to replace it
 completely in a not-so-distant future.
