Actually I think Uli should be using the Carbon routines
(FSCatalogSearch() I think, although I'm sure Uli knows more about
Carbon than I do as it happens ;->) to scan for all MacPAD.url files on
the disk, because that should really fly on HFS+ disks due to the way
HFS+ works. It's much faster than the "find" command will *ever* be,
especially on disks with lots of directories. Once you've found the
MacPAD.url files, you can then filter based on the directory they're
in, check that they're inside .app wrappers etc.

The program is a nice idea, though. It's a lot easier having one
central software update application, rather than every single app.
checking every time it gets loaded or requiring users to check
manually. Having said that, it'd be nice if Apple could integrate
MacPAD support directly into Software Update...

BTW, it doesn't seem to like being told to quit whilst it's
searching... it seems to have hung trying to obtain an NSLock in
[UKShovelAppDelegate applicationWillTerminate:] whilst the second
thread (the one doing the scanning) is trying to get an NSConditionLock
in [NSObject performSelectorOnMainThread:withObject:waitUntilDone:]
which was triggered from [UKShovelAppDelegate
findApplicationsInDirectory:].

Kind regards,

Alastair.
