NAME

       gle - Graphics Layout Engine

SYNOPSIS

       gle [options] file.gle ...

DESCRIPTION

       GLE  (Graphics  Layout  Engine)  is  a  graphics  scripting language designed for creating
       publication quality graphs, plots, diagrams, figures  and  slides.  GLE  supports  various
       graph  types  (function plots, histograms, bar graphs, scatter plots, contour lines, color
       maps, surface plots, ...) through a simple but flexible set  of  graphing  commands.  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  formulea  in graphs and figures. GLE's output formats
       include EPS, PS, PDF, JPEG, and PNG.
