This gemc release is part of a more general JLAB_VERSION release of libraries used in common across
the lab (https://data.jlab.org):

Upgraded JLab software libraries are installed on the CUE machines.  JLab Version 1.2 includes:

- QT:         4.8.5 —> 5.3.2
- geant4:   4.9.6.p03 —> 10.00.p03
- gemc:     2.1 —> 2.2
- scons_build_system: 1.1 —> 1.2
- ROOT:  5.34.21
- CCDB (new): 1.03

The "production.csh", currently pointing at 1.1, will be updated next Tuesday, Feb 10 to point to 1.2.

We now have 3 versions of libraries:

- 1.2
- 1.1
- 1.0

Details on what's in each version can be found here <https://data.jlab.org/drupal/?q=node/55>.

Users can quickly setup the environment as before:

source /site/12gev_phys/production.csh
source /site/12gev_phys/devel.csh

Users can also select custom versions using the JLAB_VERSION env variable:

setenv JLAB_ROOT /site/12gev_phys
setenv JLAB_VERSION  1.2
source $JLAB_ROOT/$JLAB_VERSION/ce/jlab.csh

Devel will include among others geant4 v 10.1, qt 5.4 and evio 4.3 support. It may include ROOT 6
support.
Starting with devel, CentOS 62 machines will no longer be supported, as they're replaced by CentOS 65.
