=head1 NAME
cpan - easily interact with CPAN from the command line
=head1 SYNOPSIS
# with arguments, installs specified modules
cpan module_name [ module_name ... ]
# with switches, installs modules with extra behavior
cpan [-cimt] module_name [ module_name ... ]
# without arguments, starts CPAN shell
cpan
# without arguments, but some switches
cpan [-ahrv]
=head1 DESCRIPTION
This script provides a command interface (not a shell) to CPAN.pm.
=head2 Meta Options
These options are mutually exclusive, and the script processes
them in this order: [ahvr]. 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.
=over 4
=item -a
Creates the CPAN.pm autobundle with CPAN::Shell->autobundle.
=item -h
Prints a help message.
=item -r
Recompiles dynamically loaded modules with CPAN::Shell->recompile.
=item -v
Print the script version and CPAN.pm version.
=back
=head2 Module options
These options are mutually exclusive, and the script processes
them in alphabetical order.
=over 4
=item c
Runs a `make clean` in the specified module's directories.
=item i
Installed the specified modules.
=item m
Makes the specified modules.
=item t
Runs a `make test` on the specified modules.
=back
=head2 Examples
# print a help message
cpan -h
# print the version numbers
cpan -v
# create an autobundle
cpan -a
# recompile modules
cpan -r
# install modules
cpan -i Netscape::Booksmarks Business::ISBN
=head1 TO DO
* add options for other CPAN::Shell functions
autobundle, clean, make, recompile, test
=head1 BUGS
* none noted
=head1 SEE ALSO
Most behaviour, including environment variables and configuration,
comes directly from CPAN.pm.
