Subject: Pass the install dir to Terrasync.
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=8cbc4df71293509edd4a08deabb94d73ee7ac87e;p=flightgear.git

Pass the install dir to Terrasync.

With Simgear commit d7d59b08a2f1a77a4247ec1a89d6ff48ed73f5c7, this
allows terrasync to be initialised from files in the install data,
which avoids downloading them again.
