Tokens

A token is any string of non-whitespace surrounded by whitespace. Each time a token begins with a minus sign (-), it is assumed to be a command and the token following it is processed. The program will ignore any token that it doesn't recognize. The tokens that are recognized as commands in a cross.inp file are -traits, -SampleSize, -TranslationTable, -end, -Cross, -case, -skip, -unskip, -quit and -start.

Note that only the first letter of these tokens is actually necessary (except for -start, -stop and -skip, which require more letters to distinguish between them).

Case is important. -Units is different from -units.

Extra whitespace is ignored, so you can put in spaces, tabs, carriage returns, etc, to format your data in an understandable fashion.
