This page holds free software that was developed as engineering tools by Ingenieurbuero Erckert.
We think that some of this software might be versatile for other users too.
The software however is not developed to commercial standards. It still holds imperfections and features that originally were planned but eventually never got implemented. Therefore all of this sofware is provided freely under the GNU publicc license.
The software is sorted by the required operating system. All packages are holding the source code, the compiled code, a brief documentation and the GNU public license agreement. The packages were archived using gtar and compressed using gzip. On most UNIX or LINUX systems the files can be unpacked using

    gunzip "name.tar.gz"
    gtar -xvf "name.tar"
