%ICON{tip}% If you use a different release for testing the workbook examples, you may need different versions of packages checkedout. Please see [[http://www.lps.umontreal.ca/twiki/bin/view/AtlasCanada/ComputingTips#How_to_determine_the_version_of][this section]] for details on how to determine the package versions.

---++ Example requirements file

This is an example of a requirements file which lives in ~/cmthome:
<verbatim>
set CMTSITE STANDALONE
set SITEROOT /data/Kits/13.0.20/
macro ATLAS_DIST_AREA ${SITEROOT}
macro ATLAS_TEST_AREA ${HOME}/testarea 
apply_tag projectArea
macro SITE_PROJECT_AREA ${SITEROOT}
macro EXTERNAL_PROJECT_AREA ${SITEROOT}
apply_tag setup
apply_tag simpleTest
use AtlasLogin AtlasLogin-* $(ATLAS_DIST_AREA)
set CMTCONFIG i686-slc4-gcc34-opt
set DBRELEASE_INSTALLED 3.1.1
</verbatim>
Note that this is for Scientific Linux 4.

Here is another example of a requirements file:
<verbatim>
set CMTSITE STANDALONE

macro PROJ_RELEASE   "latest" \
              12.0.6         "12.0.6" \
              13.0.20        "13.0.20"

set SITEROOT /data/Kits/${PROJ_RELEASE}

macro ATLAS_DIST_AREA ${SITEROOT}
macro ATLAS_TEST_AREA ${HOME}/testarea
apply_tag projectArea
macro SITE_PROJECT_AREA ${SITEROOT}
macro EXTERNAL_PROJECT_AREA ${SITEROOT}
apply_tag setup
apply_tag simpleTest
use AtlasLogin AtlasLogin-* $(ATLAS_DIST_AREA)
set CMTCONFIG i686-slc4-gcc34-opt
set DBRELEASE_INSTALLED 3.1.1
</verbatim>
This allows one to switch releases without having it "hardcoded" in SITEROOT.  For example, I can then setup as
<verbatim>
source ~/cmthome/setup.sh -tag=13.0.20,32    (for 13.0.20 32-bit)
source ~/cmthome/setup.sh -tag=12.0.7,gcc323 (for 12.0.7 running gcc 3.2.3)
</verbatim>
Note that the SITEROOT directory should at least have a softlink "latest" to one of the new releases.  Also, if you change the requirements file, remember to do a cmt config.

---++  Environment Variables

   * CVSROOT should be automatically setup to point you to 
<verbatim>
:kserver:atlas-sw.cern.ch:/atlascvs
</verbatim>

---++  Tasks at Each Login

   * Setup the cmt configuration
<verbatim>
~/cmthome/source.[c]sh -tag=xx.xx.xx[,32] 
</verbatim>

   * %ICON{stop}% (do this, or the *.csh version only if you install the [[AtlasCanada/GLite-SingleUser][gLite single-user]] version) 
<verbatim>
source ~/gLite/etc/profile.d/grid_env.sh
source ~/gLite/etc/profile.d/lcgenv.sh
</verbatim>

   * Ganga setup is *not* needed ...

<strike>(for bash) export GANGA_CONFIG_PATH=GangaAtlas/Atlas.ini <br>
(for tcsh) setenv GANGA_CONFIG_PATH !GangaAtlas/Atlas.ini
</strike>


   * set the environment variable for EDITOR
<verbatim>
(for bash) export EDITOR=emacs
(for tcsh) setenv EDITOR emacs
</verbatim>

   * authenticate Kerberos if you want access to source code
<verbatim>
kinit -4 -5 user@CERN.CH
</verbatim>

   * authenticate afs if you want to write to your CERN afs area
<verbatim>
klog
</verbatim>

   * get the grid proxy
<verbatim>
 voms-proxy-init --voms atlas:/atlas/ca
</verbatim>
