[plt-scheme] proposal for indicating planet package version numbers

To reduce confusion between PLaneT "package versions" and the version 
numbers of software packages that happen to be packaged as PLaneT 
packages... I'd like to strongly suggest that instead of having the 
PLaneT Web pages say this:

    version   Version
    1.1       0.3

that they instead say this:

    version   Version
    (1 1)     0.3

Basically, I want to never, ever see "." in a PLaneT package version 
number.  "." is already used in the version numbers of most software 
packages ever written, which means it terrific for distinguishing the 
two kinds of version numbers.  TThe sexp format proposed above is also a 
good mnemonic for the "Scheme" flavor of version number, as opposed to 
the "normal" flavor.  The sexp format also fits the different ways that 
PLaneT package version numbers are used, better than a string with dots 
in it would, and "require" forms don't use dots anyway.

If someone could make this change, I also suggest clearer terminological 
conventions, such as saying either "PLaneT Version" and "Software 
Version", and never simply saying "version".  Or invent a new word for 
"PLaneT version" -- something like "verid", which can be selected in 
"require" forms and such by a "verspec" form, only perhaps not so 

I think I suggested this before, but I don't recall seeing a rationale 
for doing it the current way.
