7 """Extract UserMetrics "actions" strings from the Chrome source.
9 This program generates the list of known actions we expect to see in the
10 user behavior logs. It walks the Chrome source, looking for calls to
11 UserMetrics functions, extracting actions and warning on improper calls,
12 as well as generating the lists of possible actions in situations where
13 there are many possible actions.
16 base/metrics/user_metrics.h
17 http://wiki.corp.google.com/twiki/bin/view/Main/ChromeUserExperienceMetrics
19 After extracting all actions, the content will go through a pretty print
20 function to make sure it's well formatted. If the file content needs to be
21 changed, a window will be prompted asking for user's consent. The old version
22 will also be saved in a backup file.
