The Free Open Source version of EWD for GT.M includes everything you need to run a complete EWD/m_apache system. In the download zip file you'll find a readme file that includes instructions on installing and configuring EWD and m_apache.
Once you've installed the routines, follow the standard instructions on this web site for using EWD.
Unless you have purchased support from M/Gateway Developments, the GT.M kit is supplied on a Do It Yourself basis, without any further support or instructions on its installation and configuration.
If you're not a GT.M expert, we recommend that you use the M/DB Installer which provides the quickest and easiest way to get up and running with EWD.
