Obtain BYCEPS#

Grab a copy of BYCEPS itself. For now, the best way probably is to clone the Git repository from GitHub:

$ git clone https://github.com/byceps/byceps.git

A new directory, byceps, should have been created.

This way, it should be easy to pull in future updates to BYCEPS using Git. (And there currently are no release tarballs anyway.)
