NAME
       cpan - easily interact with CPAN from the command line

SYNOPSIS
               # with arguments and no switches, installs specified modules
               cpan module_name [ module_name ... ]

               # with switches, installs modules with extra behavior
               cpan [-cfimt] module_name [ module_name ... ]

               # without arguments, starts CPAN.pm shell
               cpan

               # without arguments, but some switches
               cpan [-ahrvACDLO]

DESCRIPTION
       This script provides a command interface (not a shell) to
       CPAN. At the moment it uses CPAN.pm to do the work, but it
       is not a one-shot command runner for CPAN.pm.

   Meta Options
       These options are mutually exclusive, and the script
       processes them in this order: [hvCAar].  Once the script
       finds one, it ignores the others, and then exits after it
       finishes the task.  The script ignores any other command
       line options.

       -a  Creates the CPAN.pm autobundle with
           CPAN::Shell->autobundle.

       -A module [ module ... ]
           Shows the primary maintainers for the specified
           modules

       -C module [ module ... ]
           Show the "Changes" files for the specified modules

       -D module [ module ... ]
           Show the module details. This prints one line for each
           out-of-date module (meaning, modules locally installed
           but have newer versions on CPAN).  Each line has three
           columns: module name, local version, and CPAN version.

       -L author [ author ... ]
           List the modules by the specified authors.

       -h  Prints a help message.

       -O  Show the out-of-date modules.

       -r  Recompiles dynamically loaded modules with
           CPAN::Shell->recompile.

       -v  Print the script version and CPAN.pm version.

   Module options
       These options are mutually exclusive, and the script
       processes them in alphabetical order. It only processes
       the first one it finds.

       c   Runs a `make clean` in the specified module's
           directories.

       f   Forces the specified action, when it normally would
           have failed.

       i   Installed the specified modules.

       m   Makes the specified modules.

       t   Runs a `make test` on the specified modules.

   Examples
               # print a help message
               cpan -h

               # print the version numbers
               cpan -v

               # create an autobundle
               cpan -a

               # recompile modules
               cpan -r

               # install modules ( sole -i is optional )
               cpan -i Netscape::Booksmarks Business::ISBN

               # force install modules ( must use -i )
               cpan -fi CGI::Minimal URI

CREDITS
       Japheth Cleaver added the bits to allow a forced install
       (-f).

       Jim Brandt suggest and provided the initial implementation
       for the up-to-date and Changes features.

       Adam Kennedy pointed out that exit() causes problems on
       Windows where this script ends up with a .bat extension
