DESCRIPTION
This manual page documents cellx, a one-pass interpreter of the CELL language. CELL language is a simple line-oriented language for dynamic graphics drawing. cellx reads a source code written in the CELL language from the standard input or specified files. Every line in the source code is parsed and interpreted. The output is drawn on a window using SDL library via pygame module or sent to the standard output in the PostScript format.
