Subject: —config options can load non-XML files
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=6ae92b667ecdbacc185f5a9dccae0150da282171;p=flightgear.git

—config options can load non-XML files

Expand existing —-config option to read either property-XML files (as
it previously did) but for non-XML files, to parse them as command
line argument files.
