"""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:
LocalizeString(/*i18n-content*/"PRODUCT_NAME");
This script also recognises localized strings in HTML and manifest.json files:
HTML: <span i18n-content="PRODUCT_NAME"></span>
or ...i18n-value-name-1="BUTTON_NAME"...
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.
