The beginnings of the kio_z3950r slave

I just threw up the first, very rough version of kio_z3950r – a kio slave for the z39.50 protocol. This is what I’ll ultimately use for internet searches from Bookcase.

KIOSlaves, in general, have me very confused, and they are very difficult to debug. But this first version works, or at least, it allows me to search the Library of Congress server for certain query terms. Now I just need to figure out how to parse USMARC output.
