-Adds the given directory to the path list, but does not
-check if the path was already on the list (use
-\helpref{wxPathList::Member()}{wxpathlistmember} for this).
+The first form adds the given directory to the path list, if the path is not already in the list.
+If the path cannot be normalized for some reason, it returns \false.
+
+The second form just calls the first form on all elements of the given array.
+
+The {\it path} is always considered a directory but no existence checks will be done on it
+(because if it doesn't exist, it could be created later and thus result a valid path when
+\helpref{FindValidPath}{wxpathlistfindvalidpath} is called).
+
+{\bf Note:} if the given path is relative, it won't be made absolute before adding it
+(this is why \helpref{FindValidPath}{wxpathlistfindvalidpath} may return relative paths).
