- * Note: I don't have a clue what I'm doing. I just looked at the

- * johnjen@reynoldsnet.org - minor fixes with debug mode output. Consistent brace
- * use as well as indenting. More error messages put in to test for failure
- * modes with /dev/ permissions (when it happens). Note: I, like Richard, have
