CodeDepencyGraph

Instructions to make the code dependency graph on computing division machine woof.

1. Clean checkout
git clone ssh://p-mu2eofflinesoftwaremu2eoffline@cdcvs.fnal.gov/cvs/projects/mu2eofflinesoftwaremu2eoffline/Offline.git
2. Remove files that unnecessarily complicate the picture. This includes all modules, which natuallry all sit at the top dependence layer, and a few directories like Sandbox. This does actual file deletes in the release...
# Once upon a time I checked that everything would build if we source ~kutschke/LinkLoops/trim.sh
3. Create the file that contains the dependency pairs
cd Offline time /home/greenc/work/cet-is/sources/cetbuildtools/bin/code-dep-graph -v -o ../trimmed.dot >& ../trimmed.log
4. Transitive reduction and create graph
# This step issues a warning if 1 or more loops exist. # The loop is neither complete nor super informative tred trimmed.dot | dot -Tpng -o trimmed.png
5. Create graph without transitive reduction - impossible to read
dot trimmed.dot -Tpng -o trimmed_notred.png
