+Compare two RPM-format versions for equality.  The return value is like
+strcmp(), returning -1, 0, or 1 when versionA is earlier, equal to, or
+later than versionB, respectively.  Note that some comparisions featuring
+floating-point notation may compare incorrection, eg, 2.101 is considered
+later than 2.2 (101 is larger than 2) which may be incorrect per some
+projects versioning methods.
