profile-manual: Added basic XML files and updated the .gitignore

Added four chapters to the directory.  I based these chapters off
of an existing YP manual.  I also updated the .gitignore file
so that it will support ingnoring profile-manual make operations.

+<title>Getting Started with the Yocto Project</title>
+
+<para>
+    This chapter introduces the Yocto Project and gives you an idea of what you need to get started.
+    You can find enough information to set up your development host and build or use images for
+    hardware supported by the Yocto Project by reading the
+    <ulink url='&YOCTO_DOCS_QS_URL;'>Yocto Project Quick Start</ulink>.
+</para>
+
+<para>
+    The remainder of this chapter summarizes what is in the Yocto Project Quick Start and provides

+    <title>Introducing the Yocto Project</title>
+
+    <para>
+        The Yocto Project is an open-source collaboration project focused on embedded Linux development.
+        The project currently provides a build system, which is
+        referred to as the OpenEmbedded build system in the Yocto Project documentation.
+        The Yocto Project provides various ancillary tools suitable for the embedded developer
+        and also features the Sato reference User Interface, which is optimized for
+        stylus driven, low-resolution screens.
+    </para>
+
+    <para>
+        You can use the OpenEmbedded build system, which uses
+        BitBake to develop complete Linux
+        images and associated user-space applications for architectures based on ARM, MIPS, PowerPC,
+        x86 and x86-64.
+        While the Yocto Project does not provide a strict testing framework,
+        it does provide or generate for you artifacts that let you perform target-level and
+        emulated testing and debugging.
+        Additionally, if you are an <trademark class='trade'>Eclipse</trademark>
+        IDE user, you can install an Eclipse Yocto Plug-in to allow you to
+        develop within that familiar environment.

+        <itemizedlist>
+            <listitem><para><emphasis>Host System:</emphasis>  You should have a reasonably current

+                You will have the best results with a recent release of Fedora,
+                OpenSUSE, Debian, Ubuntu, or CentOS as these releases are frequently tested against the Yocto Project
+                and officially supported.
+                For a list of the distributions under validation and their status, see the

+            <listitem id='local-yp-release'><para><emphasis>Yocto Project Release:</emphasis>
+                You need a release of the Yocto Project.
+                You set that up with a local <link linkend='source-directory'>Source Directory</link>
+                one of two ways depending on whether you
+                are going to contribute back into the Yocto Project or not.

+                    Regardless of the method you use, this manual refers to the resulting local

+                        Once you have the tarball, just extract it into a directory of your choice.</para>
+                        <para>For example, the following command extracts the Yocto Project &DISTRO;
+                        release tarball

+                        with the latest developments, you should use Git commands to set up a local
+                        Git repository of the upstream <filename>poky</filename> source repository.
+                        Doing so creates a repository with a complete history of changes and allows
+                        you to easily submit your changes upstream to the project.
+                        Because you cloned the repository, you have access to all the Yocto Project development
+                        branches and tag names used in the upstream repository.</para>
+                        <para>The following transcript shows how to clone the <filename>poky</filename>
+                        Git repository into the current working directory.

+    <title>Using Pre-Built Binaries and QEMU</title>
+
+    <para>
+        Another option you have to get started is to use pre-built binaries.
+        The Yocto Project provides many types of binaries with each release.
+        See the "<ulink url='&YOCTO_DOCS_REF_URL;#ref-images'>Images</ulink>"
+        chapter in the Yocto Project Reference Manual
+        for descriptions of the types of binaries that ship with a Yocto Project
+        release.
+    </para>
+
+    <para>
+        Using a pre-built binary is ideal for developing software applications to run on your
+        target hardware.
+        To do this, you need to be able to access the appropriate cross-toolchain tarball for
+        the architecture on which you are developing.
+        If you are using an SDK type image, the image ships with the complete toolchain native to
+        the architecture.
+        If you are not using an SDK type image, you need to separately download and
+        install the stand-alone Yocto Project cross-toolchain tarball.
+    </para>
+
+    <para>
+        Regardless of the type of image you are using, you need to download the pre-built kernel
+        that you will boot in the QEMU emulator and then download and extract the target root
+        filesystem for your target machine’s architecture.
+        You can get architecture-specific binaries and filesystems from
+        <ulink url='&YOCTO_MACHINES_DL_URL;'>machines</ulink>.
+        You can get installation scripts for stand-alone toolchains from
+        <ulink url='&YOCTO_TOOLCHAIN_DL_URL;'>toolchains</ulink>.
+        Once you have all your files, you set up the environment to emulate the hardware
+        by sourcing an environment setup script.
+        Finally, you start the QEMU emulator.
+        You can find details on all these steps in the
+        "<ulink url='&YOCTO_DOCS_QS_URL;#using-pre-built'>Using Pre-Built Binaries and QEMU</ulink>"
+        section of the Yocto Project Quick Start.
+    </para>
+
+    <para>
+        Using QEMU to emulate your hardware can result in speed issues
+        depending on the target and host architecture mix.
+        For example, using the <filename>qemux86</filename> image in the emulator
+        on an Intel-based 32-bit (x86) host machine is fast because the target and
+        host architectures match.
+        On the other hand, using the <filename>qemuarm</filename> image on the same Intel-based
+        host can be slower.
+        But, you still achieve faithful emulation of ARM-specific issues.
+    </para>
+
+    <para>
+        To speed things up, the QEMU images support using <filename>distcc</filename>
+        to call a cross-compiler outside the emulated system.
+        If you used <filename>runqemu</filename> to start QEMU, and the
+        <filename>distccd</filename> application is present on the host system, any
+        BitBake cross-compiling toolchain available from the build system is automatically
+        used from within QEMU simply by calling <filename>distcc</filename>.
+        You can accomplish this by defining the cross-compiler variable
+        (e.g. <filename>export CC="distcc"</filename>).
+        Alternatively, if you are using a suitable SDK image or the appropriate
+        stand-alone toolchain is present in <filename>/opt/poky</filename>,
+        the toolchain is also automatically used.
+    </para>

+    <note>
+        Several mechanisms exist that let you connect to the system running on the
+        QEMU emulator:

+            <listitem><para>Generally, headless embedded devices have a serial port.
+                If so, you can configure the operating system of the running image
+                to use that port to run a console.
+                The connection uses standard IP networking.</para></listitem>
+            <listitem><para>SSH servers exist in some QEMU images.
+                The <filename>core-image-sato</filename> QEMU image has a Dropbear secure
+                shell (ssh) server that runs with the root password disabled.
+                The <filename>core-image-basic</filename> and <filename>core-image-lsb</filename> QEMU images
+                have OpenSSH instead of Dropbear.
+                Including these SSH servers allow you to use standard <filename>ssh</filename> and
+                <filename>scp</filename> commands.
+                The <filename>core-image-minimal</filename> QEMU image, however, contains no ssh
+                server.</para></listitem>
+            <listitem><para>You can use a provided, user-space NFS server to boot the QEMU session
+                using a local copy of the root filesystem on the host.
+                In order to make this connection, you must extract a root filesystem tarball by using the
+                <filename>runqemu-extract-sdk</filename> command.
+                After running the command, you must then point the <filename>runqemu</filename>
+                script to the extracted directory instead of a root filesystem image file.</para></listitem>
