Changeset 214

Message:

VERSION: Updated for 1.1d1.

main.c: Updated copyright statement. Updated for 1.1d1. Removed
ancient todo list. Only support 10.4 and higher - removed unnecessary
BROKEN_LSOPENFROMURLSPEC and unused DEBUG #defines. Replace
LSLaunchURLSpec with LSApplicationParameters. Added -o for arguments
(which doesn't work, delaying 1.1's release pending Apple fix).
Support app paths with -a, like open(1) does. Print file content's
UTI if possible on -f. Removed a couple of extraneous arguments to
osstatusexit. Replaced error codes with symbolic constants again.

README: Updated for 1.1d1.

-Q. Why won't launch locate non-packaged applications by their bundle
-identifier?
-
-A. This was a LaunchServices/CFBundle bug, fixed in Mac OS X 10.2.
-For example, BBEdit 6.1 for OS X was a packaged application; BBEdit
-6.5 is not, however its 'plst' resource contains a bundle ID.
-LaunchServices prior to OS X 10.2 was unable to locate BBEdit 6.5 by
-its bundle ID.
-
-Non-packaged applications usually originated as Mac OS applications,
-so they will have creators.  If you're using Mac OS X 10.1.x, try
-using the creator instead of the bundle ID as a workaround (-c instead
-of -i).

 Q. Why doesn't launch support opening items as root?
