# We're going to authenticate a self-check user.  we'll add a flag to borrowers 'selfcheck'
#
# We're in a controlled environment; we trust the user.
# So the selfcheck station will accept a patronid and issue items to that borrower.
# FIXME: NOT really a controlled environment...  We're on the internet!
#
# The checkout permission comes form the CGI cookie/session of a staff user.
# The patron is not really logging in here in the same way as they do on the
# rest of the OPAC.  So don't confuse loggedinuser with the patron user.
#
# FIXME: inputfocus not really used in TMPL
