During F2F meeting, Bonn, FOSS4G we agreed on:

• we will add configuration option to config file (no PYWPS_PROCESSES any more)
• we will create function to read the directory to pywps-core
• we have to make sure, once the files are changed, it will reload automatically (maybe documentation how to do it in apache etc. will be enough)
• @jorgejesus will investigate how to do it (keyworks: flask, docker, ....)
