This is the master directory for pgraf, the portable graphics system.
Pgraf comes in several parts, as indicated by the sub-directories of
this directory.  Metagens contains metacode generators that can be
linked to C programs to generate a metacode file containing plotting
instructions.  It also contains ``.r'' files to generate pgraf
metacode from inside the matrix manipulation program ``RLaB''.
Include contains an include file pgraf.h to be included in C programs.
Pgmain contains the main metacode reader routine.  Lolevels contains
low level subroutines that can be linked with the metacode reader
routine to generate device-specific metacode reader programs.
Lolevels also contains the makefile for making metacode reader
programs.  Pgraf documentation is now in doc and man.
