# Revision 1.10  2003/02/02 07:18:37  acli
# Moved C4/Charset.pm to C4/Interface/CGI/Output.pm
#
# Create output_html_with_http_headers function to contain the "print $query
# ->header(-type => guesstype...),..." call. This is in preparation for
# non-HTML output (e.g., text/xml) and charset conversion before output in
# the future.
#
# Created C4/Interface/CGI/Template.pm to hold convenience functions specific
# to the CGI interface using HTML::Template
#
# Modified moremembers.pl to make the "sex" field localizable for languages
# where M and F doesn't make sense
#

# Templating reservereport et shelves.
#
