Low-level FFI bindings to the libconfig
configuration file library.
This library only binds to version 1.4.9 of the libconfig
library, which is known as libconfig9 in Debian-like
distributions, including Ubuntu. It will not work with
older versions of libconfig, including the libconfig8
distributed in Ubuntu 12.04.
See below for several flags you can use to reduce
dependencies if this is a problem for you. If you disable
everything, this package will only depend on
transformers, text, hashable and deepseq.
