+hcana - Hall C ROOT/C++ analyzer
+============================================
+
+hcana is an under-development tool to analyze data from the HMS, SHMS and
+SOS spectrometers in
+[Hall C](http://www.jlab.org/Hall-C/) at [JLab](http://www.jlab.org/).
+It is being developed to replace
+the historical Hall C analyzer, ENGINE, which was written in Fortran.
+hcana will be the package used to analyze Hall C date in the 12 GeV era.
+hcana is being written in C++, using the CERN ROOT framework.  hcana is
+an extension to the Hall A analyzer, PODD.
+
+NOTE: In the process of retrieving the hcana source code, a copy of
+the Hall A PODD package will be downloaded.  The version of PODD included
+has been slightly modified for use with hcana.  For an official version
+of PODD, see the [ROOT/C++ Analyzer for Hall A](http://hallaweb.jlab.org/podd/) page.
+
+Downloading
+-----------
+
+Instructions for downloading hcana can be found in the
+[Hall C Wiki](https://hallcweb.jlab.org/wiki/index.php/ROOT_Analyzer/Git).
+
+Compiling
+---------
+hcana may be compiled with either make or scons.  Switching between these
+two build systems make require some cleanup of dependency files, binary files
+and other autogenerated files.
+
+Before compiling, type
+`source setup.sh` or `source setup.csh`
+depending on whether your shell is bash or csh.
+
+### Compiling with make
+    make
+
+### Compiling with scons
+    python ./podd/scons/scons.py
+To do the equivalent of "make clean", do
+`python ./podd/scons/scons.py -c`
+To compile the standalone codes the are part of podd, do
+`python ./podd/scons/scons.py standalone=1`
+
+Running
+-------
+Basic instructions on how to run hcana are in the
+[Hall C Wiki](https://hallcweb.jlab.org/wiki/index.php/ROOT_Analyzer/Running).
