13 | |
14 | # with switches, installs modules with extra behavior |
15 | cpan [-cimt] module_name [ module_name ... ] |

23 | =head1 DESCRIPTION |
24 | |
25 | This script provides a command interface (not a shell) to CPAN.pm. |
26 | |
27 | =head2 Meta Options |
28 | |
29 | These options are mutually exclusive, and the script processes |
30 | them in this order: [ahvr]. Once the script finds one, it ignores |
31 | the others, and then exits after it finishes the task. The script |
32 | ignores any other command line options. |
33 | |

35 | |
