It has over 100 lines in the file as displayed on my screen. It starts
off like this:
- -------------------------------------------------------------
   1. Introduction
   2. General Principles
   3. Conversion Examples

Introduction

To convert haresources files to a CIB, please use the haresources2cib.py
script. Use it like this:

 python /usr/lib/heartbeat/cts/haresources2cib.py  \
      > /var/lib/heartbeat/crm/cib.xml

Note that if you installed Linux-HA somewhere else, then the pathnames
need to change to match your installation.

Active/Active is a term which has many meanings to many people.  And,
what we mean by it is defined on the web site.  Going to what I suspect
_you_ mean by active/active is not a function of the HA software, but in
fact a function of the application.  So, even if you mean "parallel
execution of the same application" not "both nodes are doing active
work", it's permitted by Linux-HA (even release 1) - but VERY few
applications are prepared to run that way.  Many people think that
active/active is a property of the servers, not a property of the
application.  Depends on your point of view.  R2 has specific provisions
to manage truly parallel applications.

That's an error.  Should be fixed now.  Thanks for pointing it out!

No, it's just badly organized.  A good place to start might be the most
recent tutorial found here:
	http://linux-ha.org/HeartbeatTutorials

There's even a 1.5 hour video of it - in which I joke about XML too
much, but got pretty good reviews from the audience.  The slides online
have about 4.5 hours more material, but the slot I had to speak in was
only 1.5 hours - so that's all there is on the video.

As soon as they give us a permanent URL, we'll fix it :-(

	Thanks for your comments!
