dumpdb and loaddb are a lot trickier than they look. they
allow arbitrary selection expressions (totally undocumented) and
regular expression matching by attribute.

	for example:

hussar-> dumpdb -c 'str.nam = [b.*o]' -v -h -f ~/hacks/umud/hash -o ff
+> sysobj
-> wizard
+> 0
dumped 2 objects
hussar->     


	the '+>' prefix is output in verbose mode to indicate the object
was selected, and the '->' indicates it was not. the expression given
matches for all objects with a name string that has a 'b', any characters,
and an 'o'.
