DESCRIPTIONThe Debbugs::Versions::Dpkg module provides pure-Perl routines to compare dpkg-style version numbers, as used in Debian packages. If you have the libapt-pkg Perl bindings available (Debian package libapt-pkg-perl), they may offer better performance.
- Compare the two arguments as dpkg-style version numbers. Returns -1 if the first argument represents a lower version number than the second, 1 if the first argument represents a higher version number than the second, and 0 if the two arguments represent equal version numbers.
AUTHORDon Armstrong <[email protected]> and Colin Watson <[email protected]>, based on the implementation in "dpkg/lib/vercmp.c" by Ian Jackson and others.
