Pure Python implementation of rpmvercmp.

The RPM Package Manager (http://rpm.org) has a version comparision algorithm, implemented in its C library, which performs the comparison in a certain way.

In certain circumstances, where the C library is not installable (for example, on non-rpm based systems), or does not support the desired version of the python interpreter, the pure-python implementation may be useful.

$ pip install rpm_vercmp

import rpm_vercmp assert rpm_vercmp.vercmp("1.0", "1.0") == 0 assert rpm_vercmp.vercmp("1.0", "1.1") == -1

The testsuite uses rpm's test file in m4 format. The file cat be fetched from: https://raw.githubusercontent.com/rpm-software-management/rpm/master/tests/rpmvercmp.at
