-       essential, conffiles). The assumption is that all other fields
-       can be found in th available file.
-
-       But, someone proposed the idea to make it possible to
-       reconstruct a .opk from an installed package, (ie. for beaming
-       from one handheld to another). So, maybe we actually want a few

-       be guaranteed to work even in the absence of more information
-       from the available file.
-
-       28-MAR-03: kergoth and I discussed this yesterday.  We think
