=head1 NAME
dh_octave_version - check Octave version dependency for an Octave-Forge package
=head1 SYNOPSIS
B<dh_octave_version>
=head1 DESCRIPTION
B<dh_octave_version> is intended to be run from the top-level source
directory of an Octave add-on package. It checks whether the version
of the Octave program installed in the system satisfies the dependency
specified in the package's F<DESCRIPTION> file.
=head1 SEE ALSO
L<debhelper(7)>, L<dh(1)>, L<dh_octave_substvar(1)>, L<dh_octave_clean(1)>,
L<dh_octave_check(1)>, L<dh_octave_changelogs(1)>, L<dh_octave_examples(1)>
This program is meant to be used together with debhelper for Debian
packages derived from Octave-Forge packages.
It is recommended to enable it by adding the dh-sequence-octave
virtual package to Build-Depends, Build-Depends-Arch or
Build-Depends-Indep.
This is equivalent to adding dh-octave to the same field and adding
--with=octave to the dh sequencer in debian/rules, except that only
-arch/-indep/profiled builds are affected.
This is also slightly more simple in the most common case.
