# code modified by Trendsetters (from original circulation.pl)
# Please use 8-character tabs for this file (indents are every 4 characters)
#
#  rychi edit: we're just trying to issue some books. 'Trendsetters' code mostly deleted.
#    Note:  This is incomplete; implemented for a library that trusts its users and  has no fines;
#    as such, there are some circ functions that are missing and tests that are skipped.
#    
#    The issuer is a special user
#  with borrowerflag 'selfcheck' set.  The borrower has been authenticated.
#  We're going to post a barcode with a form, and check that barcode for issuability.
#  If it's issuable, we issue it.  If there's an error, we call a popup.
