+* synchronize non-GNU package descriptions with the [[http://directory.fsf.org][FSD]]
 
 Meta-data for GNU packages, including descriptions and synopses, can be
 dumped from the FSD:
 http://directory.fsf.org/wiki?title=GNU/Export&action=purge .
 We could periodically synchronize with that.
 
-See http://lists.gnu.org/archive/html/bug-guix/2013-04/msg00120.html for info
-on how to synchronize with GSRC's descriptions.

 * add a guildhall build system
 
 The Guildhall is Guile’s packaging system.  It should be easy to add a
 ‘guildhall-build-system’ that does the right thing based on guildhall
 recipes.
 
-* build-expression->derivation: define `%system' in the builder

-Would allow build expressions to have system-dependent code, like
-`glibc-dynamic-linker'.
