What is Macintosh equivalent of relaunch handler?

[Bill Vlahos]

Mark,

That is unfortunate. The 3rd party middleware tool I’m using to send command line parameters doesn’t support AppleEvents. It only supports sending command line parameters.

Please consider adding a feature that will let me catch the command line parameters for Mac apps like relaunch does for Windows.

I noticed the following command line reference in the 9.0.4 rc 1 release notes. Isn’t this the kind of thing I’m asking for? If so, how does it work?

Thank you,
