"""Verifies that a given messages.json file defines all the strings used by the
a given set of files. For file formats where it is not possible to infer which
strings represent message identifiers, localized strings should be explicitly
annotated with the string "i18n-content", for example:
This script also recognises localized strings in HTML and manifest.json files:
HTML: <span i18n-content="PRODUCT_NAME"></span>
manifest.json: __MSG_PRODUCT_NAME__
Note that these forms must be exact; extra spaces are not permitted, though
either single or double quotes are recognized.
In addition, the script checks that all the messages are still in use; if
this is not the case then a warning is issued, but the script still succeeds.

To remove this warning, either remove the unused tags from
messages.json, add the files that use the tags listed above to
remoting.gyp, or annotate existing uses of those tags with the
prefix /*i18n-content*/
