=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.
