Subject: add key Common::ThreadCount to dak.conf
X-Git-Url: https://git.decadent.org.uk/gitweb/?a=commitdiff_plain;h=57619bfe35eba89e6b0f2d2383e91590ff156763;p=dak.git

add key Common::ThreadCount to dak.conf

That is the default number of threads created for the ThreadPool() but
the value can be overwritten when calling the constructor.
