    Initial work on debhelpers for asterisk modules
    
    Initial versions (not installed yet as not to postponse the security
    fix) of debhelpers for building Debian packages:
    
    * dh_asterisk: adds substvar Asterisk:ABI for any package with an
      asterisk module.
    * A debhelper sequese, so you could use 'dh --with asterisk'

+=head1 NAME
+
+dh_asterisk - Add dependency on the ABI version of Asterisk
+
+When writing a package that builds an Asterisk module and is not built
+with Astersk itself (and hence depends on the exact binary version),
+add ${Asterisk:ABI} to the package's Depends: field in debian control
+and run dh_asterisk.
+
+If you use dh, you can run dh_asterisk using:
+
+  dh --with asterisk
+
+Otherwise run it in debian/rules after installing the modules.

+=head1 SYNOPSIS
+
+B<dh_asterisk> [S<I<debhelper options>>] [S<B<-V>[I<version>]>] [S<B<--> I<file>>]
+
+=head1 DESCRIPTION
+
+dh_asterisk is a debhelper program that is responsible for correctly
+setting the dependency on asterisk-I<asterisk-ABI-version> for a package.
+
+=head1 OPTIONS
+
+No special options of its own. Use standard debhelper options.
+
+=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.
