+/*
+    By John Walker written ages ago.
+
+    Create a sparse file.
+
+    Beat denial of service floggers to death by persuading
+    them to download a HOW_BIG pseudo GIF file which is actually
+    a holey file occupying trivial space on our server.
+
+    Make:  make gigaslam            
+    Run:   ./gigaslam
+    Output: a file named gigaslam.gif that contains something like
+            16K bytes (i.e. 2-8K blocks), but appears to be 1GB in 
+            length because the second block is written at a 1GB 
+            address.
+
+    Be careful what you do with this file as not all programs know
+    how to deal with sparse files.
+
+    Tweaked by Kern Sibbald, July 2007 to grow a file to a specified
+    size.
