.SH "NAME"
Debbugs::Versions::Dpkg \- pure\-Perl dpkg\-style version comparison
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The 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.
.SH "METHODS"
.IX Header "METHODS"
.IP "vercmp" 8
.IX Item "vercmp"
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.
.SH "AUTHOR"
.IX Header "AUTHOR"
Don Armstrong <don@donarmstrong.com> and Colin Watson
<cjwatson@debian.org>, based on the implementation in
\&\f(CW\*(C`dpkg/lib/vercmp.c\*(C'\fR by Ian Jackson and others.
