System requirements :
Mac OS X v10.4 or later. Universal binary - Intel or PowerPC.
Drag and drop an O file on to the application, and O will open in the parent folder of the file, then execute the O file.
Drag a folder, and O will open in that folder, awaiting your instructions.
Subsequent file saving will be done to the appropriate folder.
If a folder contains an on_startup file, instructions in that file will be executed
before anything else, as usual.
Folders that are extracted from the tarballs from our servers contain on_startup files that do everything that is needed to display the results, so these folders can simply be dropped on to the application.
Double clicking on the application opens a window showing the O version that it contains, along with minimal instructions for its use.
Environment variables :
If you want to use the batch system in O, or if you have stereoscopic hardware, then you will need to set some environment variables for O-on-a-stick. This you do by dropping a file called "o.env" on to the application, and that file should contain environment variable statements with the usual C-shell syntax, eg :
setenv OBAT /mydisk/mydir
setenv OTMP /mydisk/myotherdir
setenv STEREO ON
The application will remember these envs until you download a new version, or drop another o.env file.
Known issues :
Alwyn Jones provides Macintosh versions of O free of charge, and blesses the free distribution of this version.
The droplet is a single Mac OS X application bundle, which you can download as a compressed tar archive. Simply download to your mac and double-click on the tar file to get your droplet, which you can then move anywhere you want. You can even carry a copy on a memory stick take it on holiday with you (hence its name).
