Hey everyone,

Just wanted to make a quick status update on what I did this week with
LDM.

- We now have better logging of everything that's happening within LDM
and its modules, though I hope to have a single logging function with
"log level" support very soon.
- The broken menu entries and icons are now fixed.
- WWM got patched to center the window. It's currently an ugly hack
which should be changed for proper handling of the always center flag.
But at least it works.
- RDP and SSH backends are now working as they should.
- Session and Language selection no longer make LDM segfault.

The only bug I currently have on my list is WWM not exiting when the X
server is dead. That should be relatively easy to fix once I have the
time to look and learn that part of the code.

I also did a quick code cleanup recently, updating all files to follow
the coding guidelines:
 - No trailing spaces
 - 4 spaces indent (replaced single tab by 4 spaces)

For these of you using Ubuntu, I have PPA builds for maverick available
here: https://launchpad.net/~stgraber/+archive/experimental/+packages
I usually rebuild a new package every-time I commit something.

I hope to have the time to do some more cleanup and improvements next
week.
