=head1 SYNOPSIS

B<dh_installifupdown> [S<I<debhelper options>>] [B<--name=>I<name>]

=head1 DESCRIPTION

dh_installifupdown is a debhelper program that is responsible for installing
if-up, if-down, if-pre-up, and if-post-down hook scripts into package build
directories.

If a file named debian/package.if-up exists, then it is installed into
etc/network/if-up.d/package in the package build directory. Similar is done
for if-down, if-pre-up, and if-post-down.

=head1 OPTIONS

=over 4

=item B<--name=>I<name>

Look for files named debian/package.name.if-* and install them as
etc/network/if-*/name, instead of using the usual files and installing them
as the package name.
