   * Basic concept: CMSSW is the current official CMS simulation and reconstruction software framework. There are various modules (shared object files), which are dynamically linked to a main binary (called =cmsRun=), which is not touched at all by the user. These modules can be switched on/off and can be configured by job config files. It runs like this: =cmsRun job_config_file.cfg=. One can also say this in an other way: the =cmsRun= interprets the job config file. One can also extend or modify the software by creating/modifying the modules.
   * Some useful links: [[https://uimon.cern.ch/twiki/bin/view/CMS/CmsSw][twiki]], [[http://cmsdoc.cern.ch/swdev/lxr/CmsSw/source/CmsSw/src/?v=0.6.0][software cross reference]], [[https://uimon.cern.ch/twiki/bin/view/CMS/WorkBookAboutConfigFile][config language manual]], [[https://twiki.cern.ch/twiki/bin/view/CMS/TutorialSamples][useful samples]].
   * How to check out and use: download the files [[%ATTACHURL%/install_cmssw.sh][install_cmssw.sh]] and [[%ATTACHURL%/DemoAnalyzer.tar.gz][DemoAnalyzer.tar.gz]], then run the [[%ATTACHURL%/install_cmssw.sh][install_cmssw.sh]] install script. Check the directory =CMSSW_*_*_*/src/Demo/DemoAnalyzer=. Under the =bin= directory I put a quasi-automated job runner script called =go.sh=. Under the =test= directory, there are job config sample files, like: single muon sample generation by particle gun + simulation + digitalization, local reconstruction (hit collection), and CTF-KF track finding.
   * We will set up soon a mailing list on CMSSW.
