Adam Dickmeiss <adam@indexdata.dk> is playing around with a Unix command-line-utility binding for use in shellscripts and suchlike. It will probably be included along with a little family of demo/test applications in the next YAZ release.
I guess that means by default that Adam is the maintainer of the Shell-Commands binding.
To give a flavour of the Shell Commands binding, here is ZOOM's equivalent of the ``Hello World'' program: a tiny Z39.50 client that fetches and displays the MARC record for Farlow & Brett Surman's The Complete Dinosaur from the Library of Congress.
