+As of 1.9.0, this is a perl FastCGI script, so you will have to make
+sure the perl libraries are available to it. A good way of doing that
+is to install to an environment directory, as described below.
+
+<h4>Installing to an environment directory</h4>
+
+<p>The Makefile has support for installing Blërg into a directory that
+includes tools, libraries, and configuration snippets for shell and web
+servers. Use it as <code>make install-environment
+ ENV_DIR=<directory></code>. Under <directory>/etc will be
+a shell script that sets environment variables, and configuration
+snippets for nginx and apache to do the same. This should make it
+somewhat easier to use Blërg in a self-contained way.
+
+<p>For example, this will install Blërg to an environment directory
+inside your home directory:
+
+<pre>user@devhost:~/blerg$ make install-environment ENV_DIR=$HOME/blerg-env
+...
+user@devhost:~/blerg$ . ~/blerg-env/etc/env.sh
+</pre>
+
+<p>Then, you will be able to run tools like <code>blergtool</code>, and
+it will operate on data inside <code>~/blerg-env/data</code>. Likewise,
+you can include
+<code>/home/user/blerg-env/etc/nginx-fastcgi-vars.conf</code> or
+<code>/home/user/blerg-env/etc/apache-setenv.conf</code> in your
+webserver to make the CGI/FastCGI scripts to the same thing.
