> input consists of a sequence of commands. Commands are made up
of a number of tokens, depending on the syntax of the command.
Tokens are usually separated by whitespace, but need not be if
there is no ambiguity. There is no special command separator; the
next token that syntactically cannot belong to the preceding
command starts a new one. (Usually you would put a new command on
a new line, for clarity.) Tokens can be certain key words, special
characters (parentheses, commas, etc.), numbers, or double-quoted
strings. Everything is case sensitive.
