=head1 SYNOPSIS

B<dh_bugfiles> [B<-A>] [S<I<debhelper options>>]

=head1 DESCRIPTION

B<dh_bugfiles> is a debhelper program that is responsible for installing
bug reporting customization files (bug scripts and/or bug control files
and/or presubj files) into package build directories.

=head1 FILES

=over 4

=item debian/I<package>.bug-script

This is the script to be run by the bug reporting program for generating a bug
report template. This file is installed as F<usr/share/bug/package> in the
package build directory if no other types of bug reporting customization
files are going to be installed for the package in question. Otherwise,
this file is installed as F<usr/share/bug/package/script>. Finally, the
installed script is given execute permissions.

=item debian/I<package>.bug-control

It is the bug control file containing some directions for the bug reporting
tool. This file is installed as F<usr/share/bug/package/control> in the
package build directory.

=item debian/I<package>.bug-presubj

The contents of this file are displayed to the user by the bug reporting
tool before allowing the user to write a bug report on the package to the
Debian Bug Tracking System. This file is installed as
F<usr/share/bug/package/presubj> in the package build directory.

=back

=head1 OPTIONS

=over 4

=item B<-A>, B<--all>

Install F<debian/bug-*> files to ALL packages acted on when respective
F<debian/package.bug-*> files do not exist. Normally, F<debian/bug-*> will
be installed to the first package only.
