makepatch/applypatch beyond diff/patch
Ben told me that many in the SVN community are looking for a file
format that goes beyond the abilities of diff and patch, namely to
describe differences of whole directory trees.
I recommended him:
> ... the makepatch and applypatch programs by Johan Vromans. They are

I'm not an expert in the makepatch/applypatch innards, but as the
documentation states:
Note that 'applypatch' only requires the 'patch' program. It does
not rely on a shell or shell tools. This makes it possible to
apply patches on non-Unix systems.
I'd just say: please give it a try.

I think that makepatch is as old as patch itself and the format is a
single-implementation de facto standard. I don't know if Johan has
ever tried to write the specs down.

Maybe: currently, when I use makepatch on subversioned directories, I
use the '--exclude .svn' option. Depending on how properties are
stored within the .svn directories, it might be possible to include
some parts of the .svn directory and that's it. That would boil down
to a single option.
Otherwise, if you need access to the applypatch metadata directly, you
need to ask Johan, if there is room for an extension mechanism.

Took a look. Seems like a useful program... but unfortunately, it
doesn't document the patchkit format. Maybe that's a pre-existing
convention that's documented somewhere else?
The important question for Subversion is whether the format is
extensible, so we can put metadata (properties) into the patchkits
without making them incompatible with `applypatch'. Do you happen to
know the answer?
(And are there any other important questions I'm forgetting? :-) )
