+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
+
+dh_installemacsen is a debhelper program that is responsible for installing
+files used by the debian emacsen-common package into package build
+directories.
+
+It also automatically generates the postinst and prerm commands needed to
+register a package as an emacs add on package. The commands are added to
+the maintainer scripts by dh_installdeb. See L<dh_installdeb(1)>
+for an explanation of how this works.
+
+If a file named debian/package.emacsen-install exists, then it is installed
+into
+usr/lib/emacsen-common/packages/install/package in the package build
+directory. Similarly, debian/package.emacsen-remove is installed into
+usr/lib/emacsen-common/packages/remove/package . And similarly,
+debian/package.emacsen-startup is installed into
+etc/emacs/site-start.d/50<package>.el (by default).
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<-n>, B<--noscripts>
+
+Do not modify postinst/prerm scripts.
+
+=item B<--priority=>I<n>
+
+Sets the priority number of a site-start.d file. Default is 50.
+
+=item B<--flavor=>I<foo>
+
+Sets the flavor a site-start.d file will be installed in. Default is
+"emacs", alternatives include "xemacs" and "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.
