About

externaltools is a RootCore alternative that uses the waf build system.

externaltools also makes it easier to manage bundles of packages and builds a Python package under which each tool is a subpackage.

Each bundle in bundles/ contains a list of the packages and the format of each line is as follows:

[package name] [path to package (trunk, or a specific tag or branch) in svn]

Please add any additional packages.

Getting and Building the External Tools

To checkout all packages (supply your CERN username):

./repo fetch -u username 2011 2012

Then build everything:

make

Using the Packages

First source the setup script:

source externaltools/setup.sh

This adds externaltools/lib to the LD_LIBRARY_PATH and the parent directory of externaltools to the PYTHONPATH.

In a Python script:

from externaltools import MissingETUtility

Notes

The EmbeddedCorrections package requires downloading the following file separately since it is too large for svn and placing it in the share directory:

/afs/cern.ch/user/l/lhelary/public/TriggerEventNumberDimuons7TeV.root
