commit aafa53bb3e4b248e178a654883db2ba1177c5750
Author: Peter Clifton <pcjc2@xxxxxxxxx>
Date:   Thu Jan 10 00:25:20 2008 +0000

    gnetlist: Load gnetlist.scm and backend before schematic traversal.
    
    Allows gnetlist.scm and backends to define scheme procedures and
    variables which may be used to control the schematic traversal process.
    
    Since some portions of of gnetlist.scm are evaluated immediately upon
    load, yet require execution _after_  schematic traversal, these portions
    have been split out from gnetlist.scm into a new file, gnetlist-post.scm
    which is loaded after traversal.
    
    The moved definitions are those of "packages", "all-unique-nets",
    "all-nets", "all-pins", and the refdes aliasing functionality.
