    Environment: syntax
        Environment: Keyword [, keyword ..]

    Environment: example
        Environment: SunView, XView, X11R4, termcap

    The keywords usage is case insensitive.  I am extending Bill's usage 
    by adding a NOT indicator (e.g. !AIX) so that I can specify that a 
    package runs on everything "but" the specified keyword.

Doesn't it really need a richer syntax, like arbitrarily complex boolean
expressions?

Environment: ((ThisOs & ThatOption) | OtherOS) & (ThisPackage | ThatPackage)
