It seems people are quite confused ... by the different options ...
perhaps they didn't read what the patch was doing ... and thought it was
doing a different thing.

I'll explain again how I think it should work -

`openapp' is for invoking an application (if you open a terminal and want
to fire up an application, you type `openapp App.app', not `gopen
App.app')

 * to start Gorm.app, you type:

   openapp Gorm.app

   that looks for Gorm in sys/local/user/home dirs.  It finds it wherever
   it is.   This is how you start an application.


`gopen' is like clicking on a local file to open it.  If the local file
specified doesn't exist, then `gopen' should do nothing - of course -
there is no local file to click on.

 * to open the file.gorm in the current directory, you type;

   gopen file.gorm

   that *should* look for Gorm in sys/local/user/home dirs, then launch
   it to open file.gorm.

 * to open the file.gorm in the current directory using a different 
   application (not Gorm.app but, say, Another.app), you type:

   gopen -a Another.app file.gorm

   that *should* look for Another.app in sys/local/user/home dirs, then
   lauch it to open file.gorm.

 * to open an .app file in the current directory, you type:

   gopen App.app

   that will *not* look for App.app in any dirs but the local one, because
   in this case App.app is *not* the application used to open the local
   file, but the local file itself.
  
   I suppose you would use gopen here instead of openapp to make 100 % 
   sure that you are running the local version and *not* an installed one
   (say that you mistype `openapp Apl.app' might open an installed
   Apl.app, while `gopen Apl.app' will complain that the local Apl.app 
   file is not there).

 * I suppose you might as well want to open an .app file in the current
   directory using a different application (eg, an application used
   to manage other applications):

   open -a ApplicationManager.app App.app

   that will look for ApplicationManager.app in sys/local/user/home dirs, 
   launch it, and use it to open the local App.app file (directory).

the patch was instead searching the local file - but only if it was an
.app file - in the sys/local etc dirs ... which should never be done.

Some of the behaviour I explained might not be implemented yet (eg, the -a
option) ... patches to implement it are welcome.
