* mapserver/rundir/Readme.txt: New. This is a folder containing the MXD-files for conversion. The resulting MAP-file can be run from here; all Paths are relative from here so request will find its symbols, fonts, logfiles etc. * mapserver/mapfile/mapfile_header.include: Added SHAPEPATH for the Visualization of the frida-shapefiles.
