-## This script allows to compile the program as standalone, taking ROOT and BOOST from CERN AFS
-## It also takes python 2.6 from /usr/bin/python2.6 in case your default python is 2.4 like in SLC5
-## It is meant only for DEBUGGING and TESTING, and it is NOT supported.
-## 
-## Usage:
-##  - if necessary, fix the paths to BOOST, GCC, ROOT
-##  - go under HiggsAnalysis/CombinedLimit, and
-##     - if necessary, clean up a previous build with
-##         ./test/compile-standalone.sh clean
-##     - if necessary, compile the program
-##         ./test/compile-standalone.sh make
-##     - setup your environment 
-##         eval $(./test/compile-standalone.sh env)
-##  - now you can run the program
