Bug#486285: didiwiki: Didiwiki does not provide an access log [patch]

[Carlo Mandelli <camandel@gmail.com>]

To obtain a simple access log in didiwiki 0.5-6 you could try to apply this patch to use syslogd.
For example:

$ cat /etc/rsyslog.d/didiwiki.conf 
local0.*    /var/log/didiwiki.log

$ tail /var/log/didiwiki.log
Jul 12 15:54:22 hostname didiwiki: started with PID 9429
Jul 12 15:54:52 hostname didiwiki: page WikiHelp viewed from 127.0.0.1
Jul 12 15:54:58 hostname didiwiki: page WikiHelp modified from 127.0.0.1
