=head1 COMPLETION

This script has shell tab completion capability with support for several
shells.

=head2 bash

To activate bash completion for this script, put:

 complete -C vsplit vsplit

in your bash startup (e.g. F<~/.bashrc>). Your next shell session will then
recognize tab completion for the command. Or, you can also directly execute the
line above in your shell to activate immediately.

It is recommended, however, that you install modules using L<cpanm-shcompgen>
which can activate shell completion for scripts immediately.

=head2 tcsh

To activate tcsh completion for this script, put:

 complete vsplit 'p/*/`vsplit`/'

in your tcsh startup (e.g. F<~/.tcshrc>). Your next shell session will then
recognize tab completion for the command. Or, you can also directly execute the
line above in your shell to activate immediately.

It is also recommended to install L<shcompgen> (see above).

=head2 other shells

For fish and zsh, install L<shcompgen> as described above.

=head1 EXAMPLES

=head2 Split video per 15 minutes

 % vsplit --every 15min foo.mp4

=head2 Split video per 30s for WhatsApp status

 % vsplit foo.mp4 30s

=head2 Split video into 4 equiduration parts

 % vsplit foo.mp4 --parts 4

=head2 Another way to split into equiduration parts using percentage in --every

 % vsplit foo.mp4 --every 25%

=head1 CONTRIBUTING


To contribute, you can send patches by email/via RT, or send pull requests on
GitHub.

Most of the time, you don't need to build the distribution yourself. You can
simply modify the code, then test via:

 % prove -l

If you want to build the distribution (e.g. to try to install it locally on your
system), you can install L<Dist::Zilla>,
L<Dist::Zilla::PluginBundle::Author::PERLANCAR>,
L<Pod::Weaver::PluginBundle::Author::PERLANCAR>, and sometimes one or two other
Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond
that are considered a bug and can be reported to me.
