TBRootAna Tutorial June 11 (outdated)

Agenda:

• check the code out of the repository
• build the code
• run and modify the code.
• manage your problems with cvs
• tour the documentation

Checking out:

• First set CVSROOT in your .bashrc to /homes/cvs-atlas/cvsroot via:
• export CVSROOT='/homes/cvs-atlas/cvsroot
• Now you can check the code out:
• cvs checkout TBRootAna

Building:

• On dragon this is a simple procedure. Simply type 'gmake'

Run and modify:

• Open up UserALg.cxx and UserAlg.h with your favorite editor and follow the example. Remember you can reffer to the TBRootAna Users Guide, doxygen documentation and cvsweb anytime. 

Manage your problems with cvs:

• Say for example that you've played with one of the files, say ProblemFile.cxx,  and managed to cause some problem that you don't have the patience to figure out. There is a simple solution:
• rm ProblemFile.cxx
• cvs update ProblemFile.cxx
• If you would like to know exactly what files you've changed do:
• 'cvs diff' this will contact the repository and let you know what you've changed without modifying anything.
• to know the diff for a individual file 'cvs diff ProblemFile.cxx'
