  * This lists all the files in the current executible.

+ * Note that this currently pulls in all sorts of filenames

+ * contains executable lines of code, but we can't do that

  * Arguments:

- *        (up to strlen(pathname)) are included.
+ *        (up to strlen(pathname)) are included. THIS DOES NOT
