  173 +====================
  174 +There have been no efforts so far to compile ctools under Windows.

  181 + $ make check
  182 +
  183 +
  184 +Setting up your environment
  185 +===========================
  186 +Before using ctools you have to setup some environment variables.
  187 +This will be done automatically by an initialisation script that will
  188 +be installed in the bin directory.
  189 +
  190 +Assuming that you have installed ctools in the default directory
  191 +`/usr/local/gamma` you need to add the following to your `$HOME/.bashrc` or
  192 +`$HOME/.profile` script on a Linux machine:
  193 +
  194 + export CTOOLS=/usr/local/gamma
  195 + source $CTOOLS/bin/ctools-init.sh
  196 +
  197 +If you use C shell or a variant then add the following to your
  198 +`$HOME/.cshrc` or `$HOME/.tcshrc` script:
