Could a clear hint make it into the docs, please ?<br>
(Because i've been trying hard to get gdalwarp up and running in the first place. Blind me.)<br>

<p style=" margin-top:0px; margin-bottom:8px; margin-left:30px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">Proj.4 provides on-the-fly projection support to MapServer. Users whose data are in different projection systems can use this library to reproject into a common projection. It is also required for WMS, WFS or WCS services.</p><p style=" margin-top:8px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;"><a href="http://www.gdal.org/"><span style=" text-decoration: underline; color:#0057ae;">GDAL/OGR</span></a>:</p><p style=" margin-top:0px; margin-bottom:8px; margin-left:30px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">The GDAL/OGR library allows MapServer to read a variety of geospatial raster formats (GDAL) and vector formats (OGR). It can be downloaded at <a href="http://www.gdal.org/"><span style=" text-decoration: underline; color:#0057ae;">http://www.gdal.org/</span></a>.</p><p style="-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;"><br></p><p style="-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;"><br></p><p style="-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;"><br></p>> two processing options can influence the MapServer source area selection<br>
