= Depends of µRoarD =
This is a list of dependencies used by µRoarD. This list is of most interest if you plan to use µRoarD as library on a limited device.

In the following tables R/O means: R = Required, O = Optional.

== Constants ==
µRoarD depends on lots of constants exported by [[µRoar]] as included in muroar.h.
