Convert to use OptionParser for command line handling.
Move the command line option handling from the more manual "getopts" module to the full fledged "OptionParser". It has the advantage of e.g. automatically creating the Help text that is shown with the "-h/--help" option rather than having to hardcode the text and format the line breaking manually. Also, do away with the version check when invoking OfflineImap so we do not have to change the version number in three places when bumping it. Rename startup() to run() which sounds more in line what other modules call their run functions (e.g. Thread.run()).

Sets OfflineIMAP into profile mode. The program

As it runs, Python profiling information about each

thread is logged into profiledir. Please note:

This option is present for debugging and optimiza-

-a accountlist
|
||||
Overrides the accounts section in the config file.
|
||||
Lets you specify a particular account or set of

accounts to sync without having to edit the config
|
||||
file. You might use this to exclude certain
|

accounts, or to sync some accounts that you nor-
|

mally prefer not to.

-c configfile
|
||||
Specifies a configuration file to use in lieu of

the default, ~/.offlineimaprc.
|

|

-d debugtype[,debugtype...]
|
||||
Enables debugging for OfflineIMAP. This is useful
|
||||
if you are trying to track down a malfunction or
|
||||
figure out what is going on under the hood. I sug-
|
||||
gest that you use this with -1 in order to make the
|
||||
results more sensible.
|
||||
|
||||
-d now requires one or more debugtypes, separated
|
||||
by commas. These define what exactly will be
|
||||
debugged, and so far include two options: imap and
|
||||
maildir. The imap option will enable IMAP protocol
|
||||
stream and parsing debugging. Note that the output
|
||||
may contain passwords, so take care to remove that
|
||||
from the debugging output before sending it to any-
|
||||
one else. The maildir option will enable debugging
|
||||
for certain Maildir operations.
|
||||
|
||||
-f foldername[,foldername...]
|
||||
Only sync the specified folders. The "foldername"s
|
||||
are the *untranslated* foldernames. This
|
||||
command-line option overrides any "folderfilter"
|
||||
and "folderincludes" options in the configuration
|
||||
file.
|
||||
|
||||
-k [section:]option=value
|
||||
Override configuration file option. If"section" is
|
||||
omitted, it defaults to "general". Any underscores
|
||||
"_" in the section name are replaced with spaces:
|
||||
for instance, to override option "autorefresh" in
|
||||
the "[Account Personal]" section in the config file
|
||||
one would use "-k Account_Personal:autorefresh=30".
|
||||
|
||||
-o Run only once, ignoring any autorefresh setting in
|
||||
the config file.
|
||||
|

-q Run only quick synchronizations. Ignore any flag
|

updates on IMAP servers.
|

-h, --help
|
||||
Show summary of options.
|
||||
|
||||
-u interface
|
||||
Specifies an alternative user interface module to

||||
use. This overrides the default specified in the
|
||||
configuration file. The UI specified with -u will
|
||||
be forced to be used, even if its isuable() method
