doc: remove obsolete and, quite frankly, condecending information
Remove some highly obsolete and, quite frankly, condecending introductory content. For most users, downloading and especially compiling is no longer an immediate issue, so move that information to an appendix. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>

The Netwide Assembler, NASM, is an 80x86 and x86-64 assembler designed
for portability and modularity. It supports a range of object file
formats, including Linux and \c{*BSD} \c{a.out}, \c{ELF}, \c{COFF},
-\c{Mach-O}, Microsoft 16-bit \c{OBJ}, \c{Win32} and \c{Win64}. It will
-also output plain binary files. Its syntax is designed to be simple
-and easy to understand, similar to Intel's but less complex. It
-supports all currently known x86 architectural extensions, and has
-strong support for macros.
-
-
-\S{yaasm} Why Yet Another Assembler?
-
-The Netwide Assembler grew out of an idea on \i\c{comp.lang.asm.x86}
-(or possibly \i\c{alt.lang.asm} - I forget which), which was
-essentially that there didn't seem to be a good \e{free} x86-series
-assembler around, and that maybe someone ought to write one.
-
-\b \i\c{a86} is good, but not free, and in particular you don't get any
-32-bit capability until you pay. It's DOS only, too.
-
-\b \i\c{gas} is free, and ports over to DOS and Unix, but it's not
-very good, since it's designed to be a back end to \i\c{gcc}, which
-always feeds it correct code. So its error checking is minimal. Also,
-its syntax is horrible, from the point of view of anyone trying to
-actually \e{write} anything in it. Plus you can't write 16-bit code in
-it (properly.)
-
-\b \i\c{as86} is specific to Minix and Linux, and (my version at least)
-doesn't seem to have much (or any) documentation.
-
-\b \i\c{MASM} isn't very good, and it's (was) expensive, and it runs only under
-DOS.
-
-\b \i\c{TASM} is better, but still strives for MASM compatibility,
-which means millions of directives and tons of red tape. And its syntax
-is essentially MASM's, with the contradictions and quirks that
-entails (although it sorts out some of those by means of Ideal mode.)
-It's expensive too. And it's DOS-only.
-
-So here, for your coding pleasure, is NASM. At present it's
-still in prototype stage - we don't promise that it can outperform
-any of these assemblers. But please, \e{please} send us bug reports,
-fixes, helpful information, and anything else you can get your hands
-on (and thanks to the many people who've done this already! You all
-know who you are), and we'll improve it out of all recognition.
-Again.

-
-NASM has a \i{website} at

-\H{install} Installation
-
-\S{instdos} \i{Installing} NASM under MS-\i{DOS} or Windows
-
-Once you've obtained the appropriate archive for NASM,
-\i\c{nasm-XXX-dos.zip} or \i\c{nasm-XXX-win32.zip} (where \c{XXX}
-denotes the version number of NASM contained in the archive), unpack
-it into its own directory (for example \c{c:\\nasm}).
-
-The archive will contain a set of executable files: the NASM
-executable file \i\c{nasm.exe}, the NDISASM executable file
-\i\c{ndisasm.exe}, and possibly additional utilities to handle the
-RDOFF file format.
-
-The only file NASM needs to run is its own executable, so copy
-\c{nasm.exe} to a directory on your PATH, or alternatively edit
-\i\c{autoexec.bat} to add the \c{nasm} directory to your
-\i\c{PATH} (to do that under Windows XP, go to Start > Control Panel >
-System > Advanced > Environment Variables; these instructions may work
-under other versions of Windows as well.)
-
-That's it - NASM is installed. You don't need the nasm directory
-to be present to run NASM (unless you've added it to your \c{PATH}),
-so you can delete it if you need to save space; however, you may
-want to keep the documentation or test programs.
-
-If you've downloaded the \i{DOS source archive}, \i\c{nasm-XXX.zip},
-the \c{nasm} directory will also contain the full NASM \i{source
-code}, and a selection of \i{Makefiles} you can (hopefully) use to
-rebuild your copy of NASM from scratch. See the file \c{INSTALL} in
-the source archive.
-
-Note that a number of files are generated from other files by Perl
-scripts. Although the NASM source distribution includes these
-generated files, you will need to rebuild them (and hence, will need a
-Perl interpreter) if you change insns.dat, standard.mac or the
-documentation. It is possible future source distributions may not
-include these files at all. Ports of \i{Perl} for a variety of
-platforms, including DOS and Windows, are available from
-\W{http://www.cpan.org/ports/}\i{www.cpan.org}.
-
-
-\S{instdos} Installing NASM under \i{Unix}
-
-Once you've obtained the \i{Unix source archive} for NASM,
-\i\c{nasm-XXX.tar.gz} (where \c{XXX} denotes the version number of
-NASM contained in the archive), unpack it into a directory such
-as \c{/usr/local/src}. The archive, when unpacked, will create its
-own subdirectory \c{nasm-XXX}.
-
-NASM is an \I{Autoconf}\I\c{configure}auto-configuring package: once
-you've unpacked it, \c{cd} to the directory it's been unpacked into
-and type \c{./configure}. This shell script will find the best C
-compiler to use for building NASM and set up \i{Makefiles}
-accordingly.
-
-Once NASM has auto-configured, you can type \i\c{make} to build the
-\c{nasm} and \c{ndisasm} binaries, and then \c{make install} to
-install them in \c{/usr/local/bin} and install the \i{man pages}
-\i\c{nasm.1} and \i\c{ndisasm.1} in \c{/usr/local/man/man1}.
-Alternatively, you can give options such as \c{--prefix} to the
-configure script (see the file \i\c{INSTALL} for more details), or
-install the programs yourself.
-
-NASM also comes with a set of utilities for handling the \c{RDOFF}
-custom object-file format, which are in the \i\c{rdoff} subdirectory
-of the NASM archive. You can build these with \c{make rdf} and
-install them with \c{make rdf_install}, if you want them.

+
+\c ./configure
+\c make everything
+
+A number of options can be passed to \c{./configure}; see
+\c{./configure --help}.
+
+A set of Makefiles for some other environments are also available;

+
+To build the installer for the Windows platform, you will need the

+
+To build NASM from the \c{git} repository you will need a Perl and, if
+building on a Unix system, GNU autoconf.
