Description of the contents of control.pcl

This is the file used to do custom resets of the PCL interpreter,
and this will be documented as we add more.

We start by setting proper CR/LF processing so that standard UNIX
or standard DOS files get processed properly by default.

ESC & k 2 G		CR -> CR	LF -> CR+LF	FF = CR+FF

ESC ( 2 N		Set symbol set to 2N (ISO 8859-2 Latin 2)
