Getting and running xia2 from subversion

On a couple of occasions lately I have had folk asking about how to run with the xia2 direct from subversion. You should remember that there can always be problems with this (though I try to never commit breaking changes) however it's pretty straightforward. So, here we go:

* Check you have subversion installed!
* Make yourself a xia2-svn directory in wherever you keep your crystallographic software
svn co xia2core
svn co xia2
* Compose yourself a setup file which will (i) set up ccp4 then (ii) set up cctbx etc and if you like also set up labelit / XDS
* At the end of this file add

export XIA2CORE_ROOT=${HOME}/svn/xia2core
export XIA2_ROOT=${HOME}/svn/xia2
. ${XIA2_ROOT}/

for the bash shell or

setenv XIA2CORE_ROOT ${HOME}/xia2-svn/xia2core
setenv XIA2_ROOT ${HOME}/xia2-svn/xia2
source ${XIA2CORE_ROOT}/
source ${XIA2_ROOT}/

for (t)csh. For example. Then once you have sourced this setup file xia2 should work. If you want to update this please go to $XIA2_ROOT and run "svn update".

When reporting problems, please first run svn update in case I have fixed it. If I have not then please get in touch, mentioning that you are getting xia2 from svn.
