+Usage of each interpreter is of the form:
+
+<interpreter name> <program file>
+
+
+
+
+Fractran file format is one integer followed by an arbitrary number of
+fractions of the form a/b where both a and b are integers and b is not 0.
+Whitespace is not allowed inside a fraction, but is otherwise ignored.
+
+
+
+
+Thue file format is of a list of thue rules followed by the initial program
+state, as per the thue specification. Note that whitespace before and after
+the lhs or rhs of a rule is counted in that rule, and that a rule consisting
+of only whitespace (eg "   ::=   ") is treated as any other rule, not the
+termination of the rule list.
+
+
+
+
+Unlambda files should contain a single unlambda term, usually an application.
+All characters on a line after a # will be ignored, unless the # was part of
+a . or ? function. All whitespace is ignored.
+
+
+
+
+Brainfuck files should contain a number of brainfuck commands. All other
+characters are treated as whitespace and summarily ignored. The only
+restriction is that all [ loops must be closed with a corresponding ].
