+=head1 NAME
+
+ invmod - compute modular inverse of an integer
+
+=head1 SYNOPSIS
+
+ invmod <a> <m>
+
+=head1 DESCRIPTION
+
+The B<invmod> program computes the inverse of I<a>, modulo I<m>, if
+that inverse exists.  Both I<a> and I<m> are arbitrary-precision
+integers in decimal notation.  The result is written in standard
+decimal notation to the standard output.
+
+If there is no inverse, the message:
+
+ No inverse
+
+...will be printed to the standard output (an inverse exists if and
+only if the greatest common divisor of I<a> and I<m> is 1).
