extensions: improve the consistency of synopses...
extensions: improve the consistency of synopses Trying as much as possible to consistently: - use a present tense predicate followed by a direct object - verb referring directly to the functionality provided (ie. not "add command that does this" but simple "do that") - keep simple and to the point, leaving details for the long help (width is tight, possibly even more so for translations) Thanks to timeless, Martin Geisler, Rafael Villar Burke, Dan Villiom Podlaski Christiansen and others for the helpful suggestions.

Protocol between inotify clients and server:
Client sending query:
1) send protocol version number
2) send query type (string, 4 letters long)
3) send query parameters:
- For STAT, N+1 \0-separated strings:
1) N different names that need checking
2) 1 string containing all the status types to match
- No parameter needed for DBUG
Server sending query answer:
1) send protocol version number
2) send query type
3) send struct.pack'ed headers describing the length of the content:
e.g. for STAT, receive 8 integers describing the length of the
8 \0-separated string lists ( one list for each lmar!?ic status type )
