README bcal_root

This is an example program that shows how to access the BCAL06
beam test data and use it to create a ROOT file with histograms.
It uses ROOT's built-in mutex for serializing access to the
ROOT memory so this should be thread safe. To run it with
multiple processing threads, run the program with the
--nthreads=XXX option where XXX is the number of threads.

To compile this program you need a compiled JANA package
whose location given in the JLAB_HOME environment variable.

The JLAB_MY environment variable should also be set to
a directory where the compiled binaries can be installed.

Before compiling this program, you should first compile
and install the plugins for bcal06 (in src/plugins)
via: "make install". The install step will copy header
files into ${JLAB_MY}/include where they can be found
when compiling this program.

For more details on setting up JANA and building the
libraries, see:

http://www.jlab.org/Hall-D/software/wiki/index.php/HOWTO_documentation#HOWTO_Analyze_Data_Offline


Once the above packages are installed, you can build
bcal_root with just "make install". The binary will be
installed in ${JLAB_MY}/bin/${OSNAME} where the OSNAME
environment variable is set to the uname which 
should be something like "Linux".
