Removing copyright and license notices from OpenSTA sources (or any
other open source project for that matter) is illegal. This should be
obvious, but the author of OpenSTA has discovered two different cases
where the copyright and license were removed from source files that
were copied. The Chinese iEDA project from the Peng Cheng Laboratory
of the Institute of Computing Technology, Chinese Academy of Sciences
is one example. The iEDA project copied multiple OpenSTA files and
removed both the license and copyright notices, replacing them with
their own copyright and license.
