   Please use 'src/tools/polymer/polymer_grdp_to_txt.py' and
   'src/tools/polymer/txt_to_polymer_grdp.py' to modify it, if possible.
 
   'polymer_grdp_to_txt.py' converts 'polymer_resources.grdp' to a plain list of
   used Polymer components:
     ...
     iron-iron-iconset/iron-iconset-extracted.js
     iron-iron-iconset/iron-iconset.html
     ...
 
   'txt_to_polymer_grdp.py' converts list back to GRDP file.
 
   Usage:
     $ polymer_grdp_to_txt.py polymer_resources.grdp > /tmp/list.txt
     $ vim /tmp/list.txt
     $ txt_to_polymer_grdp.py /tmp/list.txt > polymer_resources.grdp
