truncate/rotate pgbouncer log using .ini settings

[Venkat Kaushik <venkat.pguser@xxxxxxxxx>]

I have setup pgbouncer successfully on CentOS6, PG9.2
pgbouncer.x86_64      1.5.4-1.rhel6     @pgdg92

I have a question regarding logging:
Currently I have 17MB of log and its growing.

17M -rw-rw-r--. 1 pgbouncer pgbouncer 17M Sep 26 12:17 /var/log/pgbouncer/pgbouncer.log

a) Is there a way (from pgbouncer.ini) to curtail/truncate/rotate logs?

b) If answer to (a) is NO, then I will come up with alternate solution,
but wanted to ask.

Thanks,
Venkat
