Subject: Generating the feed for a region is basically implemented.
X-Git-Url: https://git.toastfreeware.priv.at/philipp/winterrodeln/wrfeed.git/commitdiff_plain/c9813310fa67d77b9996c21eb2cca4841513e8a4

Generating the feed for a region is basically implemented.

MySQL 5.5 doesn't implement spatial "contains" correctly. That is not
corrected yet by the program.
