Welcome to the dml build script by Wijnand PD0MZ

This will attempt to build dml and all its dependancies on your system. It
requires sufficient free disk space to complete the build. Also note, that
if the system is used for other HAM applications, this script may remove
required dependancies for your running projects. Make sure you run this on
a system that's clean and doesn't serve production data. You have been warned.

The standard disclaimer applies that the authors cannot be held responsible
for any potential damages done to your system, rigs, hardware or mental state.
