+fenutils - Fenix Core Utilities
+===============================
+
+fenutils is a collection of utilities used in Fenix. Many of these utilities
+are defined by POSIX and are portable across UNIX and UNIX-like systems. Many
+are also capable of functioning as a drop-in replacement for the version that
+may be found on such a system.
+
+Currently, the following tools are completed, working, and POSIX-compliant:
+
+asa
+basename
+cat
+cksum
+cmp
+dirname
+echo
+false
+head
+link
+ln
+pwd
+true
+
+The following sh built-ins are completed, working, and POSIX-compliant:
+
+cd
+
+The following tools are completed and working, though not necessarily
+POSIX-compliant:
+
+tty
+
+The following tools are working, but not complete or POSIX-compliant:
+
+cal
+sh
+wc
+
+Building
+--------
+
+Currently, to build any given utility, simply compile it using your system's
+C compiler. In general, this can be done with:
+  `cc -std=c99 <util>`
+where <util> is the C file you wish to compile.
+
+Note that tty requires you to add the flag `-D_XOPEN_SOURCE=700`
+(*Is this another GNU thing? Gods, it'd better not be...)
+
+Portability
+-----------
+
+Currently, fenutils is know to be working on Linux when compiled using GCC and
+glibc and on FreeBSD when compiled using clang and <freebsd c lib>. Testing is
+in progress for other OS/compiler combinations. If you have any success on other
+UNIX{,-like} systems, let us know.
