 The name before the first colon must be at least two characters long,

 Note that when you make a mistake and call a function that is supposed to be
 defined in an autoload script, but the script doesn't actually define the
 function, the script will be sourced every time you try to call the function.
+And you will get an error message every time.

+Also note that if you have two script files, and one calls a function in the
+other and vise versa, before the used function is defined, it won't work.
+Avoid using the autoload functionality at the toplevel.
