The Usenet Oracle has pondered your question deeply. Your question
was:
Oh great and powerful Oracle, please grep your vast
stores of knowledge and answer my query:
I have been helping my girlfriend with her computer
assignments, but now she has me stumped. I've learned
VMS for Vax, and CMS for IBM, but she tells me she's
having trouble with PMS. Can you enlighten me as to what
platform PMS runs on, and what notable features it
provides?
And in response, thus spake the Oracle:
First you need to understand a little Latin. There
is suffix form that uses -gina for the feminine and -x
for the masculine. The best-known words following this
format are the Latin words for king and queen: rex and
regina.
Hence we deduce that a vax is actually a
masculinized vagina. And hence we deduce that PMS is to
the vagina what VMS is to the vax.
VMS and PMS have pretty much the same features, as
anyone familiar with both could tell you. Both are prone
to troublesome emotionalness, and alarming mood swings.
It should be noted that VMS was created mostly by
men, and that these men often acted as if they were
suffering from a "virtual menstrual syndrome." They made
highly emotional decisions, like not putting in some
great TOPS-20 features because they were thought up by
somebody in another part of DEC...
One popular operating system that doesn't suffer
from cyclical hormonal syndromes is Eunuchs.
