Important notice
A GPL violation was found in BiwaScheme prior to version 0.8.0. When I began
this project in 2007, I created BiwaScheme.Parser by largely copying the
parser of jsScheme (another lisp-in-js project; see README.md for the link).
However, I was not aware that it was released under the GPL.
Apart from this, we added many features to BiwaScheme.Parser in 15 years,
making it increasingly difficult to fix bugs or adding new features.
BiwaScheme v0.8.0 has a new parser implementation written from scratch
that is more R7RS compliant and fixes several known bugs.
