+dh_installemacsen - register an Emacs add on package

+=head1 SYNOPSIS
+
+B<dh_installemacsen> [S<I<debhelper options>>] [B<-n>] [B<--priority=>I<n>] [B<--flavor=>I<foo>]
+
+=head1 DESCRIPTION
+
+B<dh_installemacsen> is a debhelper program that is responsible for installing
+files used by the Debian B<emacsen-common> package into package build
+directories.
+
+It also automatically generates the F<postinst> and F<prerm> commands needed to
+register a package as an Emacs add on package. The commands are added to
+the maintainer scripts by B<dh_installdeb>. See L<dh_installdeb(1)>
+for an explanation of how this works.
+
+=head1 FILES
+
+=over 4
+
+=item debian/I<package>.emacsen-install
+
+Installed into F<usr/lib/emacsen-common/packages/install/package> in the
+package build directory.
+
+=item debian/I<package>.emacsen-remove
+
+Installed into F<usr/lib/emacsen-common/packages/remove/package> in the
+package build directory.
+
+=item debian/I<package>.emacsen-startup
+
+Installed into etc/emacs/site-start.d/50I<package>.el in the package
+build directory. Use B<--priority> to use a different priority than 50.

+=head1 OPTIONS
+
+=over 4
+
+=item B<-n>, B<--noscripts>
+
+Do not modify F<postinst>/F<prerm> scripts.
+
+=item B<--priority=>I<n>
+
+Sets the priority number of a F<site-start.d> file. Default is 50.
+
+=item B<--flavor=>I<foo>
+
+Sets the flavor a F<site-start.d> file will be installed in. Default is
+B<emacs>, alternatives include B<xemacs> and B<emacs20>.

+
+=head1 NOTES
+
+Note that this command is not idempotent. L<dh_prep(1)> should be called
+between invocations of this command. Otherwise, it may cause multiple
+instances of the same text to be added to maintainer scripts.
