-An XYA file is a depreciated format used to store data representing
-arbitrary numerical attributes associated with a set of points. The
-attribute values must be numeric.
-
-The format for an XYA file is:\\
-%\begin{verbatim}
-
-            first line:     \code{[attribute names]}\\
-            other lines:  \code{x y [attributes]}\\
-
-            for example:\\
-            \code{elevation, friction}\\
-            \code{0.6, 0.7, 4.9, 0.3}\\
-            \code{1.9, 2.8, 5, 0.3}\\
-            \code{2.7, 2.4, 5.2, 0.3}
-
-        The first two columns are always implicitly assumed to be $x$, $y$ coordinates.
-        Use the same delimiter for the attribute names and the data.
-
-        An XYA file can optionally end with a description of the georeference:
-
-            \code{\#geo reference}\\
-            \code{56}\\
-            \code{466600.0}\\
-            \code{8644444.0}
-
-        Here the first number specifies the UTM zone (in this case zone 56)  and other numbers specify the
-        easting and northing
-        coordinates (in this case (466600.0, 8644444.0)) of the lower left corner.
