=head1 NAME

dh_octave_check - automatically run an Octave-Forge package test suite

=head1 SYNOPSIS

B<dh_octave_check>

=head1 DESCRIPTION

B<dh_octave_check> performs the automated tests present in both F<*.m>
and F<*.cc> files in the current directory, which should be the top-level
source directory of an Octave add-on package.  It also runs the
script F<debian/check.m>, if it exists.

=head1 SEE ALSO

L<debhelper(7)>, L<dh(1)>, L<dh_octave_substvar(1)>, L<dh_octave_clean(1)>,
L<dh_octave_version(1)>, L<dh_octave_changelogs(1)>

This program is meant to be used together with debhelper for Debian
packages derived from Octave-Forge packages.
