Subject: perl plugin: bootstrap Collectd when initializing Perl interpreter
X-Git-Tag: collectd-4.2.0~49
X-Git-Url: https://git.octo.it/?a=commitdiff_plain;h=e35eea29ebc36e11bc6041a47b0f41e20d746d6c;p=collectd.git

perl plugin: bootstrap Collectd when initializing Perl interpreter

This automatically makes all symbols available at (Perl) compile time,
thus making the API built into collectd.
