+# the Apache "SetEnv" configuration directive). If the variables
+# documented below are set, they _override_ any configuation defaults
+# given in this file. 
+
+# TRACKER_HOMES is a list of trackers, in the form
+# "NAME=DIR<sep>NAME2=DIR2<sep>...", where <sep> is the directory path
+# separator (";" on Windows, ":" on Unix). 
+
+# Make sure the NAME part doesn't include any url-unsafe characters like 
+# spaces, as these confuse the cookie handling in browsers like IE.
+
+# ROUNDUP_LOG is the name of the logfile; if it's empty or does not exist,
+# logging is turned off (unless you changed the default below). 
+
+# DEBUG_TO_CLIENT specifies whether debugging goes to the HTTP server (via
+# stderr) or to the web client (via cgitb).
