The Hall-D Online Software

                             11-Sep-2013



The build system for online software uses scons. 

To build the entire tree in a development mode you need to add
the buildScripts/scripts directory to your PYTHONPATH environment
variable to access the build system libraries:

  setenv PYTHONPATH ${HDONLINE}/buildScripts/scripts:${PYTHONPATH}

where HDONLINE is set to the topmost directory (i.e. where this README
file is located).  In production mode you would instead point
PYTHONPATH to the buildScripts directory in an official release area,
e.g:

  setenv PYTHONPATH <some-release>/buildScripts/:${PYTHONPATH}

Note that official releases can only be made from the hdsys account.

By default files are installed into an architecture-dependent
directory in the indivdual package directories, into bin, lib, include
and other sub-directories.  In the case of scripts, no installation is
actually done since they are already in the correct place.

If the HALLD_INSTALL_DIR environment variable is set then
all installation files will be installed there instead (including
scripts to the ${HALLD_INSTALL_DIR}/scripts directory).  This is
typically done for official releases from the hdsys account.
