Installing

The three layers must be installed separately and sequentially (bottom-up).

First of all you have to download hyLISP. You can either checkout the Git repository using

git clone https://github.com/sassospicco/hylisp.git

or get and unpack the package using

fetch http://hylisp.org/download/hylisp-<version>.tar.gz

tar -vxzf hylisp-<version>.tar.gz

Login as root.
Make sure your FreeBSD release is a supported one (you can check with freebsd-version). Currently, only 10.1-RELEASE is supported.
Make sure you have the source tree installed on your machine under /usr/src. If not, you can
- Download it from FreeBSD repository using fetch ftp://ftp.freebsd.org/pub/FreeBSD/releases/<arch>/<release>/src.txz
- Extract it using tar -C / -vxJf src.txz
Move to the hylisp-dp directory and launch the install script with ./install.sh. This will patch the kernel source and copy the new header files to /usr/include. It will also add a simple kernel configuration named LISP inheriting from GENERIC. If you already have a tuned kernel, edit it as you please.
Move to /usr/src and rebuild+install the patched kernel with make kernel KERNCONF=LISP.
Note that routing functions are disabled by default in FreeBSD. You have to enable them by adding a gateway_enable="YES" line (and ipv6_gateway_enable="YES" as well, if necessary) in /etc/rc.conf.
Reboot and you should be done.
Optional: the original OpenLISP tools (map, mapstat and various man pages) are available, but no guarantee is made about their stability. You can patch the source tree running the script ./install-tools.sh and build+install with
```
  cd /usr/src/sbin/map/
  make depend
  make
  make install
  cd /usr/src/usr.bin/mapstat/
  make depend
  make
  make install
  cd /usr/src/share/man/man4/
  make
  make install
```

Move to the hylisp-hv directory and issue make and make install
A make install-service will install a rc.d service. Add hylisphv_enable="YES" to /etc/rc.conf to enable it.

Make sure you have expat library installed (check if /usr/local/include/expat.h exists). Otherwise, install it with pkg install expat or cd /usr/ports/textproc/expat && make clean install.
Move to the hylisp-cp directory and issue make and make install
