Compatibility
Architecture: 68k PPC

MacOS 7.1 or newer is required. Both PowerPC and 68k-based Macs are
supported. A fast machine (at least 40 MHz) with lots of RAM (probably
at least 24 Meg) is recommended. Disk space needed for Grail itself is
negligeable; you will need several Megabytes for Python and Tcl/Tk
each.

Requires Python 1.5 or newer, and Tcl/Tk 8.0 or newer to run

Fetch [MacPython 1.5.2][2] from the Garden -includes Tcl/Tk 8.0
