Made the Requirements information its own major section and moved it

between the "Getting Started Quickly" and "Getting Started Slowly" sections.
:)
Removed some of the nit-picky requirements information (i.e. GNU tar and
GNU zip).
Attempted to compact the requirements information so that it is less scary.

-    LLVM <i>may</i> compile on other platforms.  The LLVM utilities should work
-    on other platforms, so it should be possible to generate and produce LLVM
-    bytecode on unsupported platforms (although bytecode generated on one
-    platform may not work on another platform).  However, the code generators
-    and Just-In-Time (JIT) compilers only generate SparcV9 or x86 machine code.

-    Compiling LLVM requires that you have several different software packages
-    installed:
-
-    <dl compact>
-        <dt> <A href="http://gcc.gnu.org">GCC</A>
-        <dd>
-        The GNU Compiler Collection must be installed with C and C++ language
-        support.  GCC 3.2.x works, and GCC 3.x is generally supported.
-
-        <p>
-        Note that we currently do not support any other C++ compiler.
-        </p>
-
-        <dt> <A href="http://savannah.gnu.org/projects/make">GNU Make</A>
-        <dd>
-        The LLVM build system relies upon GNU Make extensions.  Therefore, you
-        will need GNU Make (sometimes known as gmake) to build LLVM.

-
-        <dt> <A href="http://www.gnu.org/software/flex">Flex</A>
-        and
-        <A href="http://www.gnu.org/software/bison/bison.html">Bison</A>
-        <dd>
-        The LLVM source code is built using flex and bison.  You will not be

-
-        <dt> <A href="http://savannah.gnu.org/projects/m4">GNU M4</A>
-        <dd>
-        If you are installing Bison on your machine for the first time, you
