+     "MathsPIC (Perl) is a development of the earlier MathsPIC (DOS) program,
+now implemented as a Perl script, being much more portable than the earlier
+program.  MathsPIC parses a plain text input file and generates a plain text
+output-file containing commands for drawing a diagram.  It produces output
+containing PiCTeX and (La)TeX commands, which may then be processed by plain
+TeX or LaTeX in the usual way.  MathsPIC also outputs a comprehensive log
+file.  MathsPIC facilitates creating figures using PiCTeX by providing an
+environment for manipulating named points and also allows the use of variables
+and maths (advance, multiply, and divide)---in short---it takes the pain out
+of PiCTeX.")
