[Rcom-l] rcom 0.97 available for download

Precisely. Let's have one source repo but _let us label any and all binary
restrictions_ more clearly so that I for one can skip over stuff that may
build for you [ Windoze ] but won't for me [ Linux, preferable on all all
ten to twelve hardware platforms supported by Debian for packages that get
uploaded ].  

While there's no automated checking of the field, there is the
SystemRequirements field in the DESCRIPTION file which is intended for
dependencies which are not R packages.  I have only seen it used for
external libraries and the like but this would seem to be a place where
one could specify any particular platform requirements as well.
