This is a modified version of chrony 4.8, with added support for the protocols
needed for NTS pools. It is mainly intended for use as a server for the
experimental pool at https://experimental.ntspooltest.org/.
For inclusion in a pool, this version of chrony requires that the pool token is
added to the file specified by the ntsauthtokenfile configuration command. See
the crhony.conf documentation for details on how to do this.
Installation instructions can be found in the INSTALL file. Note that GnuTLS and Nettle are required for NTS support.
