Hi Everyone,
I have a script that repeatedly builds a project on OS X. The
different builds are different build configurations, like Debug,
Release, etc. A user is having trouble with the project and I am
trying to get them to run the script and tee the results so he can
send them to me.

The DoJ could break up Apple's anti-trust lock on shardware/software.
There's nothing like paying $1500 for a commodity x86 board and case

Hi ALl,
Is it possible to query a control (such as a background or button) for

user previously changed it), but

I have a view that accepts input using UIKeyInput. The VC's
