parses the header line from a .koc file. This is the line that
specifies things such as the file version, and the name and version of
the offline circulation tool that generated the file. See
L<http://wiki.koha-community.org/wiki/Koha_offline_circulation_file_format>
for more information.

file).

fetches the names of the columns (and function arguments) found in the

command requires a C<cardnumber> and C<barcode>. In that case this
function returns a reference to the list C<qw( cardnumber barcode )>.
