There will only be a small number of subsets. However, quite a bit of information needs to be available about each subset:

Most of this information goes in a simple configuration file. This configuration file is flat ASCII, with the following format:

% Lines beginning with percent are comments
% (blank lines are ignored)

% Entries that start with a keyword, followed by a colon.  The
% remainder of the line is the value for that keyword.  Multi-line
% values are handled by starting successive lines with whitespace.

% The long name of the subset, for display purposes
subset: Subset Name
% The approximate size in Kbytes if copied to the local disk
localsize: 1500
% The approximate size in Kbytes required on the local disk if the
% subset is used remotely
remotesize: 50
% Any subsets that must be present before this subset can be used.
% They are in a comma separated list.
dependencies: kerberos, basic
% Where it can be installed
locations: local, fileserver, transient
% A version number for the subset.
version: 4

Subset version numbers are integers which increase each time the subset changes. Somewhere else we will keep a mapping of which subset versions are in a particular syspack release. What's missing from this configuration file is the synctree configuration and the install and remove shell scripts. These go in separate files.
