+
+  'polymer_grdp_to_txt.py' converts 'polymer_resources.grdp' to a plane list of
+  used Polymer components:
+    ...
+    core-animation/core-animation.html
+    core-animation/web-animations.html
+    core-collapse/core-collapse-extracted.js
+    core-collapse/core-collapse.css
+    core-collapse/core-collapse.html
+    core-dropdown/core-dropdown-base-extracted.js
+    ...
+
+  '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
