[CDG5] Random questions

Max,

I found it when I was trying to figure out what they used to compress
the installer "tome" files.  I have the Installer SDK somewhere -- I
was going to post a link to it once I found somewhere sane to stash
it.

If you already have your brain wrapped around InstaCompOne, I'll leave
you to it.

Anyway, it contains a MPW tool called InstaCompOneTool that can be directly invoked from the MPW shell for compressing, decompressing and viewing of InstaComp archives AND resources. It includes a guide in the DocViewer format as well (requires Apple DocViewer 1.1.1).
