source: trunk/launch/launch/main.c@ 214

Last change on this file since 214 was 214, checked in by Nicholas Riley, 18 years ago

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.
