# Edit this file by (un)commenting the libraries that you (don't) want to
# build in order to get the corresponding features in liquidsoap.

# The default file has every dependency enabled.
# It is certain that you don't need everything.
# If you don't know why you should have something, uncomment it,
# especially if it does not build for some reason.

# It is useless to add savonet packages that are not listed below,
# like ocaml-fetch, ocaml-smbclient, etc. These are not dependencies of
# liquidsoap.
