   Regular expression (regex) filters are contained in dict keys named with a
   trailing "/", such as "sources/" to operate on the "sources" list.  Regex
   filters in a dict take the form:
-    'sources/': [ ['exclude', '_(linux|mac|win)\\.cc$'] ],

   _win.cc.  The second filter then includes all files ending in _mac.cc that
