+The GNU plotutils package contains software for both programmers
+and technical users. Its centerpiece is libplot, a powerful C/C++
+function library for exporting 2-D vector graphics in many file
+formats, both vector and raster. It can also do vector graphics
+animations.
+
+libplot is device-independent in the sense that its API
+(application programming interface) does not depend on the type of
+graphics file to be exported.
+
+Besides libplot, the package contains command-line programs for
+plotting scientific data. Many of them use libplot to export
+graphics.
+
+Other ./configure options that you may want to add (provided you install
+the required fonts):
+
+--enable-ps-fonts-in-pcl enable use of PS fonts in PCL and HP-GL/2 output
+--enable-lj-fonts-in-ps enable use of LaserJet fonts in PS output
+--enable-lj-fonts-in-x enable use of LaserJet fonts on X displays
+
+This package can be useful for managing GNU Metafile plots, used by
+default in applications such as ng-spice.
