Writes a bundle file containing
a list of all modules that are both available from
CPAN and currently installed within
@INC. The file is written
to the Bundle subdirectory of
cpan_home with a name that
contains the current date and a counter; for example, Snapshot_1998_04_27_00.pm.
You can then use that file as input to the
install command to install
the latest versions of all the modules on your system:
perl -MCPAN -e 'install Bundle::Snapshot_1998_04_27_00'
