+<h2>NOTES</h2>
 
+The typical file extensions for the LAS format are .las and .laz (compressed). 
+The compressed LAS (.laz) format can be imported only if libLAS has been compiled 
+with laszip support. It is also recommended to compile libLAS with GDAL which is
+used to test if the LAS projection matches that of the GRASS location.
