This is one of the major areas which needs to be fleshed out.  The
mechanism I propose is that each set build directory will contain a
directory for each package in that set.  Each package will have a set of
PLISTs just like with current pkgsrc packages.

Right now, third-party packages can have multiple PLISTS, one containing
MI files, and MD files varying by type of platform, or by nearly
arbitrary conditions (mysql client or server PLISTS, or xemacs
PLISTs with or without MULE support to pick to examples).  Hopefully
this can be done in a standard way that will be easy to maintain.

The actual division of sets into packages still needs a lot of
discussion, as well.

A good point.  Perhaps the division into packages should keep this
goal strongly in mind, so that there are at least MD and MI packages.
This would make it easy to split into MD and MI sets as well.

At any rate, I strongly believe that the division of our current sets
into packages should be done such that no package installs into more
than one of /, /usr, /usr/share, and /usr/X11R6.  At the least, all
/usr/share packages will thus be MI.
