MIGRATING FROM RTAI/fusion TO Xenomai
-------------------------------------

This files enumerates the changes required for migrating from the
legacy RTAI/fusion to the Xenomai environment. As one would expect,
those updates are almost always related to the locations where the
name of the project is involved.

Sections 1, 5 and 6 are of a particular concern for Makefiles, whilst
section 2 will have an impact on source files. Changes exhibited by
sections 1, 3, 4, 7 and 8 should be taken in account by scripts.

In any case, there has been no change in the documented APIs.
