Subject: upkg: Print out object file offsets at high verbosity levels.
X-Git-Url: https://git.draconx.ca/gitweb/upkg.git/commitdiff_plain/45c92fd47dad10216eb2589b81f35a13cd1837f5

upkg: Print out object file offsets at high verbosity levels.

When debugging deserialize methods, it can be useful to see the actual
location within the package file of the object being deserialized.  Add
a mode to print out these raw offsets when displaying object info at
high (-vvv) verbosity levels.
