graphlet

This is updated GNU LESSER GPL Free software from University of Passau Copyright (C) 1999 University of Passau

The Graphlet System is a toolkit for graph editors and graph
(layout) algorithms. Graphlet consists of three major components:

1 The graphscript interpreter.
Graphscript is a programming language for graphs

2 The graphlet graph editor
The graphlet editor is the heart of the Graphlet system, and is
implemented in Graphscript. The editor is highly customizable, and
can be extended in Graphscript.

3 Graph layout algorithms
Graphlet comes with a set of layout algorithms, several algorithms
for spring embedders, directed acyclic graphs and trees.

This old C++ software is still usable and interesting for people interested in graph theory topics

This software is maintained here and not anymore supported by the University of Passau

This is done on a GNU/Linux computer in the year 2021 of these sources from the year 1995

The original documentation is in the doc directory as tex, postscript, html and pdf files

To use it as GNU GPL Free software it just can be re-used and not needed to register nowadays

Before compilation on Debian Linux the additional packages tcldev and tkdev must be installed.
To compile: ./autogen.sh
make
make runtests

make clean
make distclean
make cleaner

There is no support to compile this on windows or mac os-x or submit the needed changes and instructions

Also found this is the source:

int GT_No_Algorithm::check (GT_Graph& /* g */, string& message)
{
    message = "Dont worry, be happy";
    return GT_OK;
}
