30# Configuration can also be provided through the OS environment (or via
31# the Apache "SetEnv" configuration directive). If the variables
32# documented below are set, they _override_ any configuation defaults
33# given in this file.

35# TRACKER_HOMES is a list of trackers, in the form
36# "NAME=DIR<sep>NAME2=DIR2<sep>...", where <sep> is the directory path
37# separator (";" on Windows, ":" on Unix).
38
39# Make sure the NAME part doesn't include any url-unsafe characters like
40# spaces, as these confuse the cookie handling in browsers like IE.

42# ROUNDUP_LOG is the name of the logfile; if it's empty or does not exist,
43# logging is turned off (unless you changed the default below).

46# stderr) or to the web client (via cgitb).
