#
# Usage:
#  - create a new folder, let's call it cdash
#  - in that folder, do:
#    ctest -S path/to/eigen2/test/testsuite.cmake[,option1=value1[,option2=value2]]
#
# Options:
#  - EIGEN_CXX: compiler, eg.: g++-4.2
#      default: default c++ compiler
#  - EIGEN_SITE: eg, INRIA-Bdx_pc-gael, or the name of the contributor, etc.
#      default: hostname
#  - EIGEN_BUILD_STRING: a string which identify the system/compiler. It should be formed like that:
#        <OS_name>-<OS_version>-<arch>-<compiler-version>
#      with:
#        <OS_name> = opensuse, debian, osx, windows, cygwin, freebsd, solaris, etc.
#        <OS_version> = 11.1, XP, vista, leopard, etc.
#        <arch> = i386, x86_64, ia64, powerpc, etc.
#        <compiler-version> = gcc-4.3.2, icc-11.0, MSVC-2008, etc.
#  - EIGEN_EXPLICIT_VECTORIZATION: novec, SSE2, Altivec
#       default: SSE2 for x86_64 systems, novec otherwise
#       Its value is automatically appended to EIGEN_BUILD_STRING
#  - EIGEN_CMAKE_DIR: path to cmake executable
#  - EIGEN_MODE: dashboard model, can be Experimental, Nightly, or Continuous
#      default: Nightly
#  - EIGEN_WORK_DIR: directory used to download the source files and make the builds
#      default: folder which contains this script
#  - EIGEN_CMAKE_ARGS: additional arguments passed to cmake
#  - CTEST_SOURCE_DIRECTORY: path to eigen's src (use a new and empty folder, not the one you are working on)
#      default: <EIGEN_WORK_DIR>/src
#  - CTEST_BINARY_DIRECTORY: build directory
#      default: <EIGEN_WORK_DIR>/nightly-<EIGEN_CXX>
#
# Here is an example running several compilers on a linux system:
# #!/bin/bash
# ARCH=`uname -m`
# SITE=`hostname`
# VERSION=opensuse-11.1
# WORK_DIR=/home/gael/Coding/eigen2/cdash
# # get the last version of the script
# wget http://bitbucket.org/eigen/eigen2/raw/tip/test/testsuite.cmake -o $WORK_DIR/testsuite.cmake
# COMMON="ctest -S $WORK_DIR/testsuite.cmake,EIGEN_WORK_DIR=$WORK_DIR,EIGEN_SITE=$SITE,EIGEN_MODE=$1,EIGEN_BUILD_STRING=$OS_VERSION-$ARCH"
# $COMMON-gcc-3.4.6,EIGEN_CXX=g++-3.4
# $COMMON-gcc-4.0.1,EIGEN_CXX=g++-4.0.1
# $COMMON-gcc-4.3.2,EIGEN_CXX=g++-4.3,EIGEN_EXPLICIT_VECTORIZATION=novec
# $COMMON-gcc-4.3.2,EIGEN_CXX=g++-4.3,EIGEN_EXPLICIT_VECTORIZATION=SSE2
# $COMMON-icc-11.0,EIGEN_CXX=icpc
