+ *------------------------------------------------------------
+
+  This piece of code was inspired from the regsub implementation of
+  Henry Spencer. I modified it to make it compatible with the GNU Rx
+  library.
+
+  I added a more flexible interface that also allows dynamic
+  allocation of the string buffer and a function that computes the
+  length of the resulting string.
