 \section{Low Level Virtual Machine}
-This section describes the Low Level Virtual Machine (LLVM) project. It
-describes the project's aims, organisation and status.
+The Low Level Virtual Machine project (LLVM, \cite{LLVM}, \cite{Lattner:MSThesis02})
+is a framework for compiler construction. It provides its own intermediate
+representation, the LLVM IR. This is a simple language that can be used to
+expres any program in a static single assignment (SSA) form that is easy to
+reason with and transform.
+
+Additionally, LLVM provides a host of libraries to work with this IR. There is
+code for:
+\begin{itemize}
+\item reading, writing, generating and manipulating LLVM IR.
+\item transformation (optimization) of LLVM IR.
+\item codegeneration for various architectures.
+\item just-in-time codegeneration.
+\end{itemize}
+
+In addition, the LLVM project provides two frontends for generating LLVM IR:
+llvm-gcc, which uses gcc to compile a lot of languages with a LLVM backend (from
+the gcc point of view) and clang, which is a completely new project designed to
+parse and emit LLVM IR for all c-like languages (C, ObjC, C++).
