# This file is used to build ferdium-server on both x64 and arm-based for macos and linux (not tested on arm for linux).
# It also handles any corrupted node modules with the 'CLEAN' env var (set it to 'true' for cleaning)
# It will install the system dependencies except for node and python (which are still verified)
# I sometimes symlink my 'recipes' folder so that any changes that I need to do in it can also be committed and pushed independently
# This file can live anywhere in your PATH
