-## Compilation Flag

-You need to specify all the flag useful for the compilation:   like the optimization one, the mkl one .``$QP_ROOT/config`` contains ``ifort.cfg`` and ``gfortran.cfg`` files which have the compiler flags that will be used to compile the code. You can edit these files to modify the compiling option. Put the file path when calling `create_ninja_build.py`

 ## Example to create the Ninja file
 
-`create_ninja_build.py --production $QP_ROOT/config/ifort.cfg`
+`qp_create_ninja.py --production $QP_ROOT/config/ifort.cfg`
 
 # WARNING
 
-For now reload this command if you add a `IRP.f90` or `EZFIO.cfg` file or modify the `NEED_CHILDREN_MODULE`!

-If you have set the `--developement` flag in a specific module you can go in the corresponding IRPF90_temp and run `ninja` to only make the module and submodule binaries. (You can use the `-f` option too)
