=head1 list-php-versions.pl

Lists the available PHP versions on this system.

This command simply outputs a table of the installed PHP versions on your
system. Use the C<--name-only> flag to limit the output to version numbers only,
or C<--multiline> to show more details. By default only the base version numbers
are shown, but you can switch to showing the complete version with the 
C<--full-version> flag.

By default all versions available on the system will be shown, but you can
limit the list to those available for one virtual server with the C<--domain>
flag. Alternately you can force display of only versions for a particular PHP
execution mode with the C<--mode> flag followed by C<fpm>, C<fcgid> or C<cgi>.
