Subject: collectd.c: Added '-t' command line option.
X-Git-Tag: collectd-4.0.0~7^2
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=91f2edda6b4c26aa79d8746f7b900c6621e7e754;p=collectd.git

collectd.c: Added '-t' command line option.

This option allows to test the configuration only. The program immediately
exits after parsing the config file. A return code not equal to zero indicates
an error.

Some typos have been fixed as well.
