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