Subject: recipetool: parse global args early
X-Git-Tag: 2015-10~1096
X-Git-Url: https://code.ossystems.io/gitweb?a=commitdiff_plain;h=899288a1b255052a6ee0f97d42f8c4f0ec3c3140;p=openembedded-core.git

recipetool: parse global args early

This separates the argument parsing into two steps, which lets us apply global
settings like enabling debugging before the plugins load, so we can see the
paths where plugins are being loaded.
