Heirloom bc & dc provides a stand-alone project of the Heirloom Project
versions of bc(1) and dc(1) with simpler build system and no unnecessary
compatibility layers. The code has been modernized as needed to get it
working, but otherwise stays close to the original Heirloom Project
sources.

At the moment the code compiles and appears to run correctly with Glibc
and Musl under Linux as well as Sortix.

The code contains parts licensed under both 4BSD and zlib licenses. See
the COPYING file in the relevant subdirectory for more details.

The source code was gotten from https://github.com/rtomj/heirloom-project
since the original Heirloom Project repository seems to no longer ve
accessible.
