gconsync on OS X

[Richard Sheppard]

I don't know if this is the right place to ask, but maybe someone can
tell me where to go ;-)

I'm trying to find documentation on gconsync, which lives here on my
Mac (10.5.7):

/System/Library/PrivateFrameworks/GoogleContactSync.framework/Versions/
Current/Resources

Cheese-Grater:Resources ricardo$ ./gconsync ?
usage: ./gconsync [--sync clientID] [--register [0|1]] [--username
f...@bar.com] [--password pw] [--syncmode fast|slow|refresh|
pullthetruth] [--entitynames en1,en2,en3] [--report 0|1] [--httplog 0|
1]

Specifically trying to find out details of the above params, what they
mean, etc.

Cheers,

Richard
