The FidoCad/FidoCadJ format is a way to store technical drawings in a very compact text, easy to embed in an Usenet or forum messages. FidoReadPHP is a reader written in PHP able to convert on the fly the drawings and show them as images. This can be useful for forum engines wanting to use the FidoCadJ format. If you need a full fledged multiplatform editor, you may have a look at the FidoCadJ project. The FidoReadPHP project is licensed under the GPL v. 3.
