is present for FreeBSD. If you "make distfile" on FreeBSD, you will soon have a tar.gz file suitable for deploying to other systems (complete with the expected "configure" script, etc). This latter relies (at least for now) on the GNU auto??? tools. (I like autoconf okay, but someday I hope to write a custom Makefile.in and dispense with automake, which is somewhat odious.) As part of this, I've cleaned up some of the conditional compilation options, added make-foo to construct archive.h dynamically (it now contains some version constants), and added some useful informational files.
