   6 """Extract UserMetrics "actions" strings from the Chrome source.
   7
   8 This program generates the list of known actions we expect to see in the
   9 user behavior logs.  It walks the Chrome source, looking for calls to
  10 UserMetrics functions, extracting actions and warning on improper calls,
  11 as well as generating the lists of possible actions in situations where
  12 there are many possible actions.
