To install Pgraf:

1. Put the contents of include where you like to put include files.

2. In metagens, type make and put libpgc.a where you like to put
   library files.

3. In lolevels, type make.  Edit Makefile to make BIN point to
   where you like to install binaries.  Type make install.

4. Put the man directory in your MANPATH, or put the contents where
   you like to put man pages.

5. If you are using RLaB, put the files pgraf.r and pgdemo.r (in
   metagens) where RLaB can find it.  Try loading these two files
   and typing ``pgdemo()'' inside RLaB.

Notes: If you are incorporating pgraf into a C program, do only
steps 1-4.  If you just want to use pgraf in RLaB, do only steps
3-5.
