pkg_patch status

[Ivan Voras]

Weekly status: started working on second milestone, progressing a bit
slowly but within schedule.

For the record: the format of the +CONTENTS file is way too ugly to be
allowed to survive :) Someone should replace it with XML or at least
make it reasonably parseable instead of it being treated as a kludgy
variety of a batch file / shell script with some parts of it being
executed in certain contexts. It looks like the only way to
deterministically determine the result of package addition prescribed
in +CONTENTS might be to "execute" it line by line in a virtual
machine / sandbox, which I'm leaving for a future exercise.
