* Some man pages to write.
* Get rid of the lump of code in patch mpglib. Rewrite using code from mpg123?
* Get libilbc packages instead of the built-in libilbc.
* Maybe install phoneprov files below /etc - they seem use editable
* install upstream dahdi span_config file
  * add patch to un-duplicate file
  * verify that switching execution 50 -> 40 is not a problem
* Patch upstream to install missed manpages:
  * doc/aelparse.8
  * doc/smsq.8
  * utils/astman.1
