File cge_pl_files.tar.Z contains a portion of the PEXlib sample
implementation of the Common Open Systems Environment -	Common
Graphics Environment extension for PEX 5.1 version 2.  This is
all the	PEXlib changes except the texture map utilities	and
the color utilities.
 
These files are	not fully tested, but are placed here so that
CGE extension implementers can use the code and	provide	feedback.
 
This tar file was created with:
 
  tar -cvFf-  *		> cge_pl_files.tar
  compress -v cge_pl_files.tar
 
so to recover the files, use:
 
  uncompress < cge_pl_files.tar.Z | tar -xvpf-
