 This will install also the following hotwheels packages: core, io, timestep. 
 The `[tested]` tag will install the versions of the dependencies used to test the release (`v0.0.0alpha` in this case).
-You can now test the installed modules running the `hotwheels.checkup` script that will execute all `test_*` C,python and bash files:
 
-```bash
-python -m hotwheels.checkup hotwheels
-```
-
-The tests will be run using envirnoment varialbe `CC` for the C ompiler (will default to `gcc`), `MPICC` for the MPI compiler (will default to `mpicc`),   `CXX` and `MPICXX` for the c++ version (will default to `g++` and `mpicxx` respectively). 
-
-The PM run needs the `gsl` and `fftw3` to be installed. They should be either in a standard path (`/usr/{lib,include}`) or in your compiler search path (namely, in your `C_INCLUDE_PATH`, `CPLUS_INCLUDE_PATH`, and `LD_LIBRARY_PATH` env variables).
