*********************************************************************************
!!!! There is a problem with the current configuration environment !!!!
To run the tests of this package, the following variable(s) need to be defined :
FIO_ROOT : The root directory of the fio package
installation: git clone git://git.kernel.dk/fio.git. run make for
build
tested version: fio-2.1.1
The variables can be defined as environment variables (eg. with bash "export") or
passed to the configure command (e.g. ./configure FIO_ROOT=/opt/fio/ ).
The variables should point to the directory which contain
/engines,/examples,etcsubdirs.
