+## The 'buglink_base' value is a string that can be used to form a URL
+## by appending a bug number.  If viewvc sees something that looks
+## like a bug number in a log message (eg. "bug 12345" or "#12345"), it
+## will be displayed as a link to the bug in your bug tracking system.
+##
+## For a Bugzilla installation, you probably want to set this to
+## something like "http://hostname/show_bug.cgi?id=".  For the Debian
+## bug tracker, you might use
+## "http://hostname/cgi-bin/bugreport.cgi?bug=".
+##
+## If 'buglink_base' is not set, then bug tracker links won't be
+## generated.
+##
+#buglink_base = http://example.com/show_bug.cgi?id=
+
 ## root_as_url_component: Interpret the first path component in the URL
 ## after the script location as the root to use.  This is an
 ## alternative to using the "root=" query key. If ViewVC is configured
