[redurgam]

trying these for fun on arch linux for the aur, appears successful 100%, but then doesn't work yet. not sure where i went off track.

$ multifm -h

use example from wiki
$ multifm etc/multifm.json etc/flex_25khz_lpf.json

in my case there were no config files (json files) listed in the install_manifest.txt, nor manually directed, so none for the installed package
navigating back to the src directory (location of json files), i get this:

i don't know why it constantly references back to the /src directories
i'm not sure what to try next. anyway, sounds like a cool project. i may have to try on the recommended debian if i can't get this to work.
