69 For building ffado you can set different options as listed below. You have to
70 specify them only once, scons will save the last value you used and re-use
71 that.
72 To really undo your settings and return to the factory defaults, remove the
73 "cache"-folder and the file ".sconsign.dblite" from this directory.
74 For example with: "rm -Rf .sconsign.dblite cache"

76 Currently it seems as if only the BEBOB is kind-of-working, thats why only BEBOB
