"CodeWeavers makes a free downloadable version of
CrossOver Plugin 1.0.1 for those users who wish to try our software
before choosing to purchase it.
This demonstration version will let you use all of the CrossOver
functionality, except that from time to time, you will be given a
reminder to purchase our product. Please remember that buying our
product is one of the best ways to support the Wine project.
Also, if you use the free version of our product, and later
choose to purchase CrossOver, the installation process is very
smooth and simple, and you will lose none of your settings or
installed plugins."
