# Here's the deal. With ACS 4.0.1 .vuh files aren't supported with templates.
# Thats why I had to do this crazy deal with the global ad_conn, set ad_conn(file)
# and adp_parse_ad_conn_file.... What all that does is call a .tcl file
# which makes some db querries, then that .tcl file calls ad_return_template to return its
# template.

# DRB: This is mildly insane.  Either we should implement templated virtual URLs or 
# package authors should live with ugly URLs.
