=== Tag Versions ===

As a convenient run directory and to make changes to reconstruction settings, it is recommended to check out the package InDetRecExample. The correct version number associated with the release of your choice has to be used (the current version under CVS HEAD can have new settings which are not understood by existing releases). To determine the version of InDetRecExample, use the get_tag script: 
{{{
get_tag InnerDetector/InDetExample/InDetRecExample 
}}}
This gives a version associated to each release, or you can specify the release as second parameter to the above command. Alternatively you can look at the tag collector or the release area: 
{{{
cat \ 
 /afs/cern.ch/atlas/software/builds/AtlasReconstruction/14.2.0/InnerDetector/InDetExample/InDetRecExample/cmt/version.cmt 
}}}
 (note that in the release 12 series, the release number is subtracted by 10, for instance 2.0.3 instead of 12.0.3) 

in your work area check it out, specifying the concrete version:
{{{
cd ${HOME}/InDetReco
cmt co -r InDetRecExample-01-09-04-04 InnerDetector/InDetExample/InDetRecExample
}}}
or
{{{
cvs co -r TrkValTools-00-05-01 -d Tracking/TrkValidation/TrkValTools/root offline/Tracking/TrkValidation/TrkValTools/root
}}}
