This directory contains the subset of XTL required by LyX.
The full distribution includes extensive tests and documentation.
If you encounter compiler errors in xtl code when compiling LyX please
get a copy of the full distribution and run the regression tests on your
system. Report any problems found to the xtl mailing list.
