GLE is a hi quality graphics package for scientists.  GLE
combines a user friendly interface with a full range of
facilities for producing publication quality graphs, diagrams,
posters and slides.

It provides LATEX quality fonts together with a flexible 
graphics module which allows the user to specify any feature 
of a graph (down to the line width of the subticks for example)

Complex pictures can be drawn with user defined subroutines and 
simple looping structures.

The SURFACE utility allows hidden line surface plotting.

The CONTOUR utility allows contour plots. 

The MANIP utility allows columns of data to be manipulated.

The FITLS utility allows arbitrary equations to be fitted to 
data.

Current device drivers support DECWINDOWS, REGIS, TEK4010, all PC 
graphics cards, VT100's, HP-Plotters, PostScript Printers, EPSON 
Printers and LaserJet Printers.

CGLE runs on both VAX-VMS and PC's, giving an identical user interface
on both platforms.

Some scientific journals now recommend that graphs 
be submitted in GLE format.

The gle installation files are split into 4 zip files:

	GLE32D_1.ZIP	Core GLE, with PC - screen driver
	GLE32D_2.ZIP	PostScript Driver, and Expanded Memory versions
	GLE32D_3.ZIP	Bitmap device drivers (epson) and extra fonts.
	GLE32D_4.ZIP	Utilities, surface plotting, hpgl driver.
	
Use PKUNZIP.EXE to extract the installation kit from these
files, you don't need all four, just the ones you want to use.

(PKUNZIP.EXE is available from most ftp sites)

e.g.

FTP> ascii
FTP> get gle32d.txt		! this file
FTP> binary 
FTP> get gle32d_1.zip		
FTP> get gle32d_2.zip		! PostScript and expanded memory (optional)
FTP> get gle32d_3.zip		! Bitmap and extra fonts (optional)
FTP> get gle32d_4.zip		! HPGL and utilities (optional)
FTP> exit
C:\> mkdir tmp			! Make temp dir for installation files
C:\> cd tmp
C:\TMP> pkunzip ..\gle32d_*.zip		! create installation files
C:\TMP> del gle32d_*.zip		! delete uploaded files to save space
	(You MUST copy PKUNZIP.EXE to the same directory so 
	that INSTALL.EXE can find it)
C:\TMP> copy \zip\pkunzip.exe	! change \zip\ to where you keep pkunzip.exe
	(These files could now be copied to floppies for installation
	on other PC's)
C:\TMP> install
	(and answer idiot-proof questions!)

C:\TMP> cgle		(To execute the Screen version)
	(Then Press F3 to load an example and F10 to draw it)

		Please try and distribute GLE within your
		area to avoid multiple transfers.
