These are explained in the manual pages and in the usage messages. Most programs are ``case-sensitive''; almost all options must start with an upper-case letter. We have tried to choose letters of the alphabet which stand for the argument so that they will be easy to remember. Each argument specification begins with a hyphen (except input file names; see below), followed by a letter, and sometimes a number or character string immediately after the letter. <I>Do not</I> space between the hyphen, letter, and number or string. <I>Do</I> space between options.
