+.Os
+.Sh NAME
+.Nm regmath
+.Nd "Mathematics libraries for Regina REXX interpreter"
+.Sh DESCRIPTION
+.Nm
+consists of two separate collections of utility functions for use with the Regina REXX interpreter.
+These closely mirror the functions contained in the
+.Em RxMath
+library provided on IBM systems, and the
+.Em RexxMath
+library provided for use with Amiga Rexx.
+As it stands, the
+.Nm
+collections will not work with another REXX interpreter.
+.Pp
+Details of usage are in the full manual, which is normally found at:
+.br
+.Pa %%DOCSDIR%%/regmath.pdf
+(if installed).
+.Sh SEE ALSO
+The original author's web site at
+.Em http://pages.interlog.com/~pjtm/
