+This should demonstrate the use of LD_PRELOAD.
+
+    hallo:	uses virgin puts(3) and readdir(3)
+    myhallo:	uses modified puts(3) and readdir(3)
+
+If you set the environment 
+
+    LD_PRELOAD=`pwd`/libmy.so.1.0.1
+
+the "hallo" should use the modified versions of the above
+funtions too.
+
+The modification is visibable, as puts(3) prints an
+extra string before the real output, and readdir(3) skips
+any directory entry starting with 'M'.
+
+No considerations done about race conditions and other nice things.
+It is just an nice example…
