ImportDicomFiles: Look for Python interpreter in PATH Some environments (in particular the official Docker image for Python) use a different path. `env' will lookup the given command in the PATH directories like shells do (though without the overhead), thus making the script more portable (it's conventional to have /usr/bin/env present everywhere).

This sample shows how to replace the decoder of DICOM images that is
built in Orthanc, by the GDCM library.

A production-ready version of this sample, is available in the
offical Web viewer plugin:
