.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This script provides a command interface (not a shell) to \s-1CPAN\s0. At the
moment it uses \s-1CPAN\s0.pm to do the work, but it is not a one-shot command
runner for \s-1CPAN\s0.pm.
.Sh "Meta Options"
.IX Subsection "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.
.IP "\-a" 4
.IX Item "-a"
Creates the \s-1CPAN\s0.pm autobundle with CPAN::Shell\->autobundle.
.IP "\-A module [ module ... ]" 4
.IX Item "-A module [ module ... ]"
Shows the primary maintainers for the specified modules
.IP "\-C module [ module ... ]" 4
.IX Item "-C module [ module ... ]"
Show the \f(CW\*(C`Changes\*(C'\fR files for the specified modules
.IP "\-D module [ module ... ]" 4
.IX 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 This prints one line for each out-of-date module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 \s-1CPAN\s0).
Each line has three columns: module name, local version, and \s-1CPAN\s0
version.
.IP "\-L author [ author ... ]" 4
.IX Item "-L author [ author ... ]"
List the modules by the specified authors.
.IP "\-h" 4
.IX Item "-h"
Prints a help message.
.IP "\-O" 4
.IX Item "-O"
Show the out-of-date modules.
.IP "\-r" 4
.IX Item "-r"
Recompiles dynamically loaded modules with CPAN::Shell\->recompile.
.IP "\-v" 4
.IX Item "-v"
Print the script version and \s-1CPAN\s0.pm version.
.Sh "Module options"
.IX Subsection "Module options"
These options are mutually exclusive, and the script processes them in
alphabetical order. It only processes the first one it finds.
.IP "c" 4
.IX Item "c"
Runs a `make clean` in the specified module's directories.
.IP "f" 4
.IX Item "f"
Forces the specified action, when it normally would have failed.
.IP "i" 4
.IX Item "i"
Installed the specified modules.
.IP "m" 4
.IX Item "m"
Makes the specified modules.
.IP "t" 4
.IX Item "t"
Runs a `make test` on the specified modules.

Most behaviour, including environment variables and configuration,
comes directly from \s-1CPAN\s0.pm.
