.SH DESCRIPTION
.B epix 
is a powerful, flexible, lightweight, text-based preprocessor for
creating mathematically accurate, publication-quality line figures in
.B LaTeX. 
Plots and picture objects are specified entirely in Cartesian
coordinates, not in
.B LaTeX
picture coordinates.  Output resizes robustly, and may include
mathematical typography.
.B epix
uses enhancements to the
.B LaTeX
picture environment: Sunil Podar's
.B epic.sty
and Conrad Kwok's
.B eepic.sty
packages. Color figures may be generated from
.B epix
output with the
.B pstcol.sty
or
.B color.sty
packages. The included shell script
.B laps
converts
.B LaTeX
to PostScript. The shell script
.B elaps
converts .eepic to Encapsulated PostScript.
.P 
The source code, samples files, and primary documentation are
available from the project home page:

The latest stable version is also available from CTAN:

.P
.B epix
is implemented as a 
.B C++
library (libepix.a), header (epix.h), and a shell script (epix). An 
.B epix
source file is a 
.B C++
program that calls high-level library drawing functions. Under
direction of the shell script, the source file is compiled. The
resulting executable prints the .eepic file, with output redirected to
the specified file. 
.P

.B epix
is primarily for 2-dimensional plotting. There is good-quality wire
mesh plotting, but no hidden line removal yet.

.SH PYTHON WRAPPER
Andrew Sterian has written a Python wrapper,
.B pyepix
that requires Python 2.2 but does not require either a compiler or GNU
.B bash.
.B pyepix
(a *nix tarball and a Windows package) is available from the
.B epix
home page.

.SH DOCUMENTATION
Complete documentation is distributed with the "complete" source
package, and may be downloaded in several formats from the
.B epix
home page.
