	If I understand correctly, you're suggesting the following:

	newpdb = pdb_Load(file from ~/.palm/install);
	oldpdb = the version of 'newpdb' installed on the Palm;

	if (oldpdb doesn't exist ||
	    newpdb->creationtime > oldpdb->creationtime ||
	    (newpdb->creationtime == oldpdb->creationtime &&
	     newpdb->modnum > oldpdb->modnum))
		install newpdb;

This seems reasonable. Do you want to submit a patch? Does anyone see any
problems with this?

	One kinda-related problem I just noticed: when InstallNewFiles()
overwrites an existing database, it doesn't update the cached copy of the
database header. This could lead to inconsistencies.
