+Bro-aux relies on the following libraries and tools, which need to be installed
 before you begin with the installation:
 
-    * Libpcap
-	   If libpcap is already installed on the system, by default Bro
-	   will use that one.  Otherwise, it falls back to a version shipped
-	   with the Bro distribution.
+    * Libpcap headers and libraries
+       Network traffic capture library
 
     * Flex
        Flex is already installed on most systems, so with luck you can
        skip having to install it yourself.
 
-    * Bison or byacc
-	   These come with many systems, but if you get errors compiling
-	   parse.y, you will need to install them.  bison is available
-	   from GNU sites such as ftp.gnu.org.
+    * Bison
+       This comes with many systems, but if you get errors compiling
+       parse.y, you will need to install it.
 
     * BIND8 headers and libraries
        These are usually already installed as well.
 
-    * Autotools
-	   If you have checked the source out from Bro's Subversion
-	   repository, you need the autotools suite installed.  In this
-	   case, run "./autogen.sh" first right after the check out.
-	   Otherwise the installation steps below will fail.
+    * OpenSSL headers and libraries
+        For analysis of SSL certificates by the HTTP analyzer, and 
+        for encrypted Bro-to-Bro communication. These are likely installed,
+        though some platforms may require installation of a 'devel' package
+         for the headers.
+
+    * CMake 2.8 or greater
+       CMake is a cross-platform, open-source build system, typically
+       not installed by default.  See http://www.cmake.org for more
+       information regarding CMake and the installation steps below for
+       how to use it to build this distribution.
 
 Bro can also make uses of some optional libraries if they are found at
 installation time:
 
-    * OpenSSL
-           For analysis of SSL certificates by the HTTP analyzer, and 
-           for encrypted Bro-to-Bro communication.
-
     * Libmagic
       For identifying file types (e.g., in FTP transfers).
