README explaining compilation and installation procedure
Source of the precompiler (eco_prec) for ECO C++
Source of some demos including:

A little library of classes for dealing with graphs and performing layout (based on the Sugiyama algorithm). They show an interesting way to handle fictitous vertices, using extenders.
A simple graph editor written in Tcl/Tk and using the above mentioned library. It permits to manage more than one drawing and more than one orientation. Sugiyama based layout is supported. Great flexibility is achived in choosing different orientations for the execution of Sugiyama algorithm and for visualization.

All software has been tested on the following platforms:

Linux
IBM Aix
Sun Solaris
DEC OSF

with G++ 2.7.2 and recent version of FLEX and BISON, for demo application you need Tcl (version 7.6) with Tk (version 4.2).
