+=head1 SYNOPSIS
+
+ use OpenSSL::Util;
+
+ $versiondiff = cmp_versions('1.0.2k', '3.0.1');
+ # $versiondiff should be -1
+
+ $versiondiff = cmp_versions('1.1.0', '1.0.2a');

+
+ $versiondiff = cmp_versions('1.1.1', '1.1.1');

+=head1 DESCRIPTION
+
+=over
+
+=item B<cmp_versions "VERSION1", "VERSION2">
+
+Compares VERSION1 with VERSION2, paying attention to OpenSSL versioning.
+
+Returns 1 if VERSION1 is greater than VERSION2, 0 if they are equal, and
+-1 if VERSION1 is less than VERSION2.
