* PriMan's header file. Contains constant definitions, function protypes,
* and global variables.
*
* Set tab stops to 4 when editing this file.
*
* Every source file #includes this, but we only want one of them to
* actually define the global variables (and the rest to just declare
* them). So I use Eddy Carroll's trick of prefixing all definitions by a
* keyword that gets set to nothing by one file, and "extern" by all the
* rest. Hence, one file should #define MAIN, and it will be that file
* which actually defines the variables.
