[galaxy-dev] Addind new datatype - best practice

Hi Galaxy community,

I would like to add custom datatypes to my Galaxy server without editing any Galaxy files if possible. I've already created and renamed a second config/datatype.conf file. Both files are listed into galaxy.ini (variable datatypes_config_file). But what about the new datatype Class ? For example if it's a binary class, how can I add this class without editing the binary.py file or any other file (if it's possible) ?

Thanks in advance, Floreline
