-; * Elements on new line in each form must be indented the same amount
-; * No space/newline after open parens
-; * No form longer than 50 lines
-; * Top level multiline forms must be separated by exactly one space
-; * No line longer than 120 characters
-; * No use of unexported symbols in other packages
-; * No tabs
-; * Only one space between elements in a form on a single line
-; * in-package must be first line in file unless file is package.lisp

-; * No lines that are only whitespace
-; * No empty lines at end of file
