We've now implemented an OS_type field in a package's DESCRIPTION file,
which if set has to match .Platform$OS.type (possible values "unix" and
"windows"). CRAN has set up some overrides and added this field to
packages known to be Unix-only or Windows-only, but authors should do so
for themselves in future.
Unsuitable packages will not be offered by available.packages(), will not
be installed by R CMD INSTALL, and R CMD check will select --no-install.
This happens in R-devel and R-patched, and is intended to simplify
automated installation and checking.
