Even in the age of OOP one must develop algorithms. Nassi-Shneiderman diagrams are a well known tool to describe an algorithm in a graphical way. The package offers some macros for generating those diagrams in a LaTeX document.

The package provides the most important elements of a Nassi-Shneiderman diagram, including processing blocks, loops, mapping conventions for alternatives, etc. Diagrams are drawn using the picture environment (using pict2e for preference).

See also pict2e.
