More complex output can be created by relying on GLE's scripting language, which is full featured with subroutines, variables, and logic control.

GLE relies on LaTeX for text output and supports mathematical formula in graphs and figures.

GLE's output formats include EPS, PS, PDF, JPEG, and PNG.

The GLE software dates back to the early 1990s[3] and it is still under active development.

[4] GLE is available for all major operating systems including Microsoft Windows, Mac OS X, and Unix.
