Looking for usage and examples of pglobject class found in libpq++

I am looking for documentation and/or examples *(beyond the one installed
with ~postgresql-7.0.2 located in ...
/src/interfaces/libpq++/examples/testlo.cc)  on how to use the pglobject
class.  In particular, I want to take a large object and insert it into a db
table.

Anyone out there having fun with Large Objects using the libpq++
interface????
