/* A testing tool that tries to emit message given as argument
* to the journal, and, if succceds (at least per journald retcode).
* If whole operation is successful there is need to actually check
* that message is present in journal (also veryfing journal read perms)
*
* Retcodes: 0 - success
* 1 - wrong arguments (expects exactly one)
* 2 - failed to open journal for writing
* 3 - failed to actually write message to journal
*
* Part of the testbench for rsyslog.
