In order to use the BitKeeper repository version of NTP you will have
to have the following tools installed:

	autoconf	2.50 or later (we use 2.52)
	automake	(we use 1.5)
	lynx

Lynx is used to generate the COPYRIGHT file.  Don't ask.

You can get bitkeeper by visiting:

	http://www.bitkeeper.com/ 

We are using bitkeeper under their free license program.  You can use
bitkeeper for free to access NTP, too.  If you have questions about this,
please ask.  The license is pretty easy to read.
 
Once you have installed bitkeeper, you can clone any NTP repository.

You can get the ntp-stable repository by either of the following commands:

     bk clone bk://www.ntp.org/home/bk/ntp-stable ntp-stable

     bk clone bk://ntp.bkserver.net/ntp-stable ntp-stable

You can get the ntp-dev repository by either of the following commands:

     bk clone bk://www.ntp.org/home/bk/ntp-dev ntp-dev

     bk clone bk://ntp.bkserver.net/ntp-dev ntp-dev

The IPV6 patch has been applied:

     bk clone bk://www.ntp.org/home/bk/ntp-dev-ipv6 ntp-dev-ipv6

     bk clone bk://ntp.bkserver.net/ntp-dev-ipv6 ntp-dev-ipv6

The ntp-dev-ipv6 repository will be merged back in to the ntp-dev repo
as soon as the code is stable.

If you are stuck behind a firewall that blocks access to the default port
used by bitkeeper (14690) but you can use port 80 instead, you can use
http as a bk transport mechanism.  Just use:

     bk clone http://ntp.bkserver.net/REPO REPO

Finally, it's possible to use SMTP as a bk transport mechanism.  So far, we
haven't tried this.

Once you have obtained the sources, do the following:

	cd REPO
	bk -r edit		to check out the files
	autoreconf -f -i	generates configure and Makefile.in's

and you should be ready to go.  You will get some warning messages from
autoreconf.  Ignore these messages.

You can update your repository by incanting:

	cd REPO
	bk pull
