Hi @yegor256 ,
Does 0pdd works with private repositories?

Today i've observer this issue:

set -x;set -e;set -o pipefail;cd /tmp/0pdd20171202-4-2tshup/dgroup/docker-unittests && pdd -q -f /tmp/pdd.xml20171202-3012-1xu83h0: pid 3041 exit 255 (not zero):
+ set -e
+ set -o pipefail
+ cd /tmp/0pdd20171202-4-2tshup/dgroup/docker-unittests
+ pdd -q -f /tmp/pdd.xml20171202-3012-1xu83h0

ERROR: /tmp/0pdd20171202-4-2tshup/dgroup/docker-unittests/src/main/java/org/dgroup/dockertest/yml/package-info.java; @todo found, but puzzle can't be parsed in line #6, most probably because TODO is not followed by a puzzle marker, as this page explains: https://github.com/yegor256/pdd#how-to-format

Looks like my format of the @todo messages is wrong.
They should be written in accordance to https://github.com/yegor256/pdd#how-to-format.
