=item B<-a>, B<--arch>
-Act on all architecture dependent packages.
+Act on architecture dependent packages that should be built for the
+build architecture.
=item B<-i>, B<--indep>
=item B<-s>, B<--same-arch>
-This is a smarter version of the -a flag, that is used in some rare
-circumstances. It understands that if the control file lists "Architecture: i386"
-for the package, the package should not be acted on on other architectures. So
-this flag makes the command act on all "Architecture: any" packages, as well
-as on any packages that have the current architecture explicitly specified.
-Contrast to the -a flag, which makes the command work on all packages that
-are not architecture independent.
+This used to be a smarter version of the -a flag, but the -a flag is now
+equally smart.
=item B<-N>I<package>, B<--no-package=>I<package>
shows which build system would be automatically selected, or which one
is manually specified with the I<--buildsystem> option.
-=item B<--help-buildsystem>
-
-Print detailed help about a build system which would be auto-selected or which
-is manually specified with the L<--buildsystem> option.

-=head2 Doc directory symlinks
-
-Sometimes it is useful to make a package not contain a /usr/share/doc/package
-directory at all, instead placing just a dangling symlink in the binary
-package, that points to some other doc directory. Policy says this is ok if
-your package depends on the package whose doc directory it uses. To
-accomplish this, just don't tell debhelper to install any documentation
-files into the package, and use dh_link to set up the symlink (or do it by
-hand), and debhelper should do the right thing: notice it is a dangling
-symlink and not try to install a copyright file or changelog.

=head2 udebs
Debhelper includes support for udebs. To create a udeb with debhelper,
