| 8 | This script allows to run a benchmark on a set of different compilers/compiler options. |
| 9 | It takes two arguments: |
| 10 | - a file defining the list of the compilers with their options |
| 11 | - the .cpp file of the benchmark |
| 12 | |
| 13 | Examples: |

| 15 | $ ./bench_multi_compilers.sh basicbench.cxxlist basicbenchmark.cpp |
