  19   'polymer_grdp_to_txt.py' converts 'polymer_resources.grdp' to a plane list of
  20   used Polymer components:
  21     ...
  22     iron-iron-iconset/iron-iconset-extracted.js
  23     iron-iron-iconset/iron-iconset.html
  24     ...
  25
  26   'txt_to_polymer_grdp.py' converts list back to GRDP file.

  28   Usage:
  29     $ polymer_grdp_to_txt.py polymer_resources.grdp > /tmp/list.txt
  30     $ vim /tmp/list.txt
