+## System requirements 
+
+- A Linux or Mac OS X system
+- A C++ compiler implementing the [C++-11 standard](http://www.stroustrup.com/C++11FAQ.html) <font color="red"><b>(NEW)</b></font>
+    - Unfortunately, many systems have compilers that predate C++-11 support.
+    - You may need to build your own C++ compiler or upgrade your operating system.
+- [Boost C++ libraries (version 1.44 or later)](http://www.boost.org/)
+    - If you build your own boost, you _must install it_ using `bjam install`.
+    - Older versions of Boost _may_ work, but problems have been reported with command line option parsing on some platforms with older versions.
+- [GNU Flex](http://flex.sourceforge.net/)
