We used the \fIexprtest\fR, \fIexprtest2\fR, and \fIpolytest\fR programs, in
the \fImathbase\fR directory, to test the general expression and polynomial
routines.  These programs can be helpful to the user since they show how a
particular expression or polynomial will be parsed.  Consult the headers at
the top of the source files \fIexpr_test.c\fR, \fIexpr_test2.c\fR, and 
\fIpoly_test.c\fR, in the \fImathbase\fR directory, to see how these 
programs work.
