+	<longdescription>The llvm-gcc command is the LLVM C front end. It is a modified version of gcc that compiles C/ObjC programs into native objects, LLVM bitcode or LLVM assembly language, depending upon the options.
+
+By default, llvm-gcc compiles to native objects just like GCC does. If the -emit-llvm and -c options are given then it will generate LLVM bitcode files instead. If -emit-llvm and -S are given, then it will generate LLVM assembly.
+
+Being derived from the GNU Compiler Collection, llvm-gcc has many of gcc's features and accepts most of gcc's options. It handles a number of gcc's extensions to the C programming language. See the gcc documentation for details.</longdescription>

+	<longdescription>Low Level Virtual Machine (LLVM) is:
+   1. A compilation strategy designed to enable effective program optimization across the entire lifetime of a program. LLVM supports effective optimization at compile time, link-time (particularly interprocedural), run-time and offline (i.e., after software is installed), while remaining transparent to developers and maintaining compatibility with existing build scripts.
+   2. A virtual instruction set - LLVM is a low-level object code representation that uses simple RISC-like instructions, but provides rich, language-independent, type information and dataflow (SSA) information about operands. This combination enables sophisticated transformations on object code, while remaining light-weight enough to be attached to the executable. This combination is key to allowing link-time, run-time, and offline transformations.
+   3. A compiler infrastructure - LLVM is also a collection of source code that implements the language and compilation strategy. The primary components of the LLVM infrastructure are a GCC-based C and C++ front-end, a link-time optimization framework with a growing set of global and interprocedural analyses and transformations, static back-ends for many popular (and some obscure) architectures, a back-end which emits portable C code, and a Just-In-Time compilers for several architectures.
+   4. LLVM does not imply things that you would expect from a high-level virtual machine. It does not require garbage collection or run-time code generation (In fact, LLVM makes a great static compiler!). Note that optional LLVM components can be used to build high-level virtual machines and other systems that need these services.</longdescription>
