BaCon is a free BASIC to C translator for Unix-based systems,
which runs on most Unix/Linux/BSD platforms, including MacOSX. It intends
to be a programming aid in creating tools which can be compiled on different
platforms (including 64bit environments), while trying to revive the days of
the good old BASIC.

BaCon can be described as a translator, a converter, a source-to-source
compiler, a transcompiler or a transpiler. It also can be described as a
very elaborate preprocessor to C.
