No Mac is complete? Nothing like shilling your own product, is there?
From OS/2? Think again, twit: this is classic Unix, and has been on vanilla X systems for a lot longer than OS/2 had to die. And where do you think IBM got it from anyway? Try 'AIX'.
Farthest from my mind, however, is this incredible download of super-shitty software - how many meg was it? The Unix original was about 40 KB on x86-based machines running Solaris.
I like it when people sell good products online. I get FURIOUS when they try to rip their fellow netizens and Mac users off!
