+  echo is a replacement for the "echo" command builtin to cmd.exe
+  on Windows, to get a Unix eqvivalent behaviour when running commands
+  like:
+    $> echo "hello" | mysql
+
+  The windows "echo" would have sent "hello" to mysql while
+  Unix echo will send hello without the enclosing hyphens
+
+  This is a very advanced high tech program so take care when
+  you change it and remember to valgrind it before production
+  use.
