cpan-outdated - detect outdated CPAN modules in your environment

       Tokuhiro Matsuno

       This script prints a list of outdated CPAN modules on your machine.

       This is the same feature as 'CPAN::Shell->r', but "cpan-outdated" is much faster and uses less memory.

       This script can be integrated with the cpanm command.

       cpan-outdated - detect outdated CPAN modules in your environment

       This script by default prints the outdated distribution as in the CPAN distro format, i.e:
       "A/AU/AUTHOR/Distribution-Name-0.10.tar.gz" so you can pipe it into CPAN installers, but with the "-p"
       option it can be tweaked to print the module's package names.

       If you wish to manage a set of modules separately from your system perl installation and not install
       newer versions of "dual life modules" that are distributed with perl, the "--exclude-core" option will
       make cpan-outdated ignore changes to core modules. Used with tools like cpanm and its "-L
       --local-lib-contained" and "--self-contained" options, this facilitates maintaining updates on standalone
       sets of modules.

       For some tools, such as cpanm, installing from packages could be a bit more useful since you can track to
       see the old version number which you upgrade from.
