=head1 NAME

cpan - easily interact with CPAN from the command line

=head1 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]

=head1 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.

=head2 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.

=over 4

=item -a

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

=item -A module [ module ... ]

Shows the primary maintainers for the specified modules

=item -C module [ module ... ]

Show the C<Changes> files for the specified modules

=item -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 This prints one line for each out-of-date module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.

=item -L author [ author ... ]

List the modules by the specified authors.

=item -h

Prints a help message.

=item -O

Show the out-of-date modules.

=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. It only processes the first one it finds.

=over 4

=item c

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

=item f

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

=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 ( sole -i is optional )
	cpan -i Netscape::Booksmarks Business::ISBN

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

=head1 TO DO


=head1 BUGS

* none noted

=head1 SEE ALSO

Most behaviour, including environment variables and configuration,
comes directly from CPAN.pm.

=head1 SOURCE AVAILABILITY

This source is part of a SourceForge project which always has the
latest sources in CVS, as well as all of the previous releases.

	http://sourceforge.net/projects/brian-d-foy/

If, for some reason, I disappear from the world, one of the other
members of the project can shepherd this module appropriately.

=head1 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

It looks like you specified 'install' as an argument to cpan(1). This
script is not the CPAN.pm prompt and doesn't understand the same commands.
In fact, doesn't require the extra typing. You probably just want to
list the modules you want to install:

	cpan @args
