I explicitly release liblx into the public domain (to the extent that I
can; there is one file - keysyms - which is a derivative work of
something else, and portions of some files in doc/ are derivatives of
X11R6.3 documentation files).

In jurisdictions where this is not possible, the statements in the
various files that they are in the public domain should be interpreted
as the closest available approximation, probably something along the
lines of "you have a license to use this file in any way for any
purpose".
