characters ('?' and '*' and '[..]' character classes) in the files.

=head1 SHARED DEBHELPER OPTIONS
The following command line options are supported by all debhelper programs.

as on any packages that have the current architecture explicitly specified.

=item B<-N>I<package>, B<--no-package=>I<package>
Do not act on the specified package even if an -a, -i, or -p option lists
the package as one that should be acted on.
+=item B<--ignore=>I<file>
+
+Ignore the specified file. This can be used if debian/ contains a debhelper
+config file that a debhelper command should not act on. Note that
+debian/compat, debian/control, and debian/changelog can't be ignored, but
+then, there should never be a reason to ignore those files.
+
+For example, if upstream ships a debian/init that you don't want
+dh_installinit to install, use --ignore=debian/init
+
=item B<-P>I<tmpdir>, B<--tmpdir=>I<tmpdir>
Use "tmpdir" for package build directory. The default is debian/<package>
Exclude an item from processing. This option may be used multiple times,
to exclude more than one thing.
-=item B<-A>, B<-all>
+=item B<-A>, B<--all>
Makes files or other items that are specified on the command line take effect
in ALL packages acted on, not just the first.
If none are given, debhelper programs default to acting on all packages listed
in the control file.

From time to time, major non-backwards-compatible changes need to be made

=head2 Other notes
In general, if any debhelper program needs a directory to exist under
debian/, it will create it. I haven't bothered to document this in all the
man pages, but for example, dh_installdeb knows to make debian/<package>/DEBIAN/
before trying to put files there, dh_installmenu knows you need a
-debian/<package>/usr/lib/menu/ before installing the menu files, etc.
+debian/<package>/usr/share/menu/ before installing the menu files, etc.
Once your package uses debhelper to build, be sure to add
debhelper to your Build-Depends line in debian/control. You should
-build-depend on a verson of debhelper equal to (or greater than) the
-debhelper compatability level your package uses. So if your package used
-compatability level 4:
+build-depend on a version of debhelper equal to (or greater than) the
