New Revision: 43840

  Break the porters handbook out into individual chapters
  like our other books (fdp primer, handbook dev handbook, etc).
  I've done some small naming changes for cleaner chapters
  but not much.
  Thumbs up:      wblock, mat

-    <para>The &os; Ports Collection is the way almost everyone
-      installs applications ("ports") on &os;.  Like everything
-      else about &os;, it is primarily a volunteer effort.
-      It is important to keep this in mind when reading this
-      document.</para>
-    <para>In &os;, anyone may submit a new port, or volunteer
-      to maintain an existing port if it is unmaintained&mdash;you
-      do not need any special commit privileges to do so.</para>

-    <title>Making a New Port Yourself</title>
-    <para>So, you are interested in making your own port or
-      upgrading an existing one?  Great!</para>
-    <para>What follows are some guidelines for creating a new port for
-      &os;.  If you want to upgrade an existing port, you should
-      read this and then read <xref linkend="port-upgrading"/>.</para>
-    <para>When this document is not sufficiently detailed, you should
-      refer to <filename>/usr/ports/Mk/</filename>, which
-      all port Makefiles include.  Even if you do not hack Makefiles
-      daily, it is well commented, and you will still gain much
-      knowledge from it.  Additionally, you may send specific
-      questions to the &a.ports;.</para>
-    <note>
-      <para>Only a fraction of the variables
-	(<varname><replaceable>VAR</replaceable></varname>) that can
-	be overridden are mentioned in this document.  Most (if not
-	all) are documented at the start of
-	<filename>/usr/ports/Mk/</filename>; the others
-	probably ought to be.  Note that this file uses a non-standard
-	tab setting: <application>Emacs</application> and
-	<application>Vim</application> should recognize the setting on
-	loading the file.  Both &; and &man.ex.1; can be set
-	to use the correct value by typing
-	<command>:set tabstop=4</command> once the file has been
-	loaded.</para>

-      <note>

-      <title>Writing the Description Files</title>
-      <para>There are two description files that are required for
-	any port, whether they actually package or not.  They are
-	<filename>pkg-descr</filename> and
-	<filename>pkg-plist</filename>.  Their
-	<filename>pkg-</filename> prefix distinguishes them from other
-	files.</para>
-      <sect2>
-	<title><filename>pkg-descr</filename></title>
-	<para>This is a longer description of the port.  One to a few
-	  paragraphs concisely explaining what the port does is
-	  sufficient.</para>
-	<note>
-	  <para>This is <emphasis>not</emphasis> a manual or an
-	    in-depth description on how to use or compile the port!
-	    <emphasis>Please be careful if you are copying from the
-	    <filename>README</filename> or manpage</emphasis>; too
-	    often they are not a concise description of the port or
-	    are in an awkward format (e.g., manpages have justified
-	    spacing, which looks particularly bad with monospaced
-	    fonts).</para>
-	</note>
-	<para>A well-written <filename>pkg-descr</filename> describes
-	  the port completely enough that users would not have to
-	  consult the documentation or visit the website to understand
-	  what the software does, how it can be useful, or what
-	  particularly nice features it has.  Mentioning certain
-	  requirements like a graphical toolkit, heavy dependencies,
-	  runtime environment, or implementation languages help users
-	  decide whether this port will work for them.</para>
-	<para>Include a URL to the official WWW homepage.  Prepend
-	  <emphasis>one</emphasis> of the websites (pick the most
-	  common one) with <literal>WWW:</literal> (followed by single
-	  space) so that automated tools will work correctly.  If the
-	  URI is the root of the website or directory, it should be
-	  terminated with a slash.</para>
-	<note>
-	  <para>If the listed webpage for a port is not available, try
-	    to search the Internet first to see if the official site
-	    moved, was renamed, or is hosted elsewhere.</para>
-	</note>
-	<para>The following example shows how your
-	  <filename>pkg-descr</filename> should look:</para>
-	<programlisting>This is a port of oneko, in which a cat chases a poor mouse all over
-the screen.
- :
-      </sect2>
-      <sect2>
-	<title><filename>pkg-plist</filename></title>
-	<para>This file lists all the files installed by the port.  It
-	  is also called the <quote>packing list</quote> because the
-	  package is generated by packing the files listed here.  The
-	  pathnames are relative to the installation prefix (usually
-	  <filename>/usr/local</filename>.
-	  If the
-	  port creates directories during installation, make sure to
-	  add <literal>_at_dirrm</literal> lines to remove them when the
-	  package is deleted.</para>
-	<para>Here is a small example:</para>
-	<programlisting>bin/oneko
-_at_dirrm lib/X11/oneko</programlisting>
-	<para>Refer to the &man.pkg-create.8; manual page for details
-	  on the packing list.</para>
-	<note>
-	  <para>It is recommended that you keep all the filenames in
-	    this file sorted alphabetically.  It will make verifying
-	    the changes when you upgrade the port much easier.</para>
-	</note>
-	<note>
-	  <para>Creating a packing list manually can be a very tedious
-	    task.  If the port installs a large numbers of files,
-	    <link linkend="plist-autoplist">creating the packing list
-	      automatically</link> might save time.</para>
-	</note>
-	<para>There is only one case when
-	  <filename>pkg-plist</filename> can be omitted from a port.
-	  If the port installs just a handful of files, and perhaps
-	  directories, the files and directories may be listed in the
-	  variables <varname>PLIST_FILES</varname> and
-	  <varname>PLIST_DIRS</varname>, respectively, within the
-	  port's <filename>Makefile</filename>.  For instance, we
-	  could get along without <filename>pkg-plist</filename> in
-	  the above <filename>oneko</filename> port by adding the
-	  following lines to the <filename>Makefile</filename>:</para>
-	<programlisting>PLIST_FILES=	bin/oneko \
-		man/man1/oneko.1.gz \
-		lib/X11/app-defaults/Oneko \
-		lib/X11/oneko/cat1.xpm \
-		lib/X11/oneko/cat2.xpm \
-		lib/X11/oneko/mouse.xpm
-PLIST_DIRS=	lib/X11/oneko</programlisting>
-	<para>Of course, <varname>PLIST_DIRS</varname> should be left
-	  unset if a port installs no directories of its own.</para>
-	<note>
-	  <para>Several ports can share a common directory.  In that
-	    case, <varname>PLIST_DIRS</varname> should be replaced by
-	    <varname>PLIST_DIRSTRY</varname> so that the directory is
-	    removed only if empty, otherwise it is silently ignored.
-	    <varname>PLIST_DIRS</varname> and
-	    <varname>PLIST_DIRSTRY</varname> are equivalent to using
-	    <literal>_at_dirrm</literal> and <literal>_at_dirrmtry</literal>
-	    in <filename>pkg-plist</filename>, as described in
-	    <xref linkend="plist-dir-cleaning"/>.</para>
-	</note>
-	<para>The price for this way of listing port's files and
-	  directories is that you cannot use command sequences
-	  described in &man.pkg-create.8;.  Therefore, it is suitable
-	  only for simple ports and makes them even simpler.  At the
-	  same time, it has the advantage of reducing the number of
-	  files in the ports collection.  Please consider using this
-	  technique before you resort to
-	  <filename>pkg-plist</filename>.</para>
-	<para>Later we will see how <filename>pkg-plist</filename>

-	    <buildtarget>fetch</buildtarget> cannot find the required

-	  <para>The <buildtarget>extract</buildtarget> target is run.

-	    <varname>DISTDIR</varname> and unpacks it into a temporary

-      </procedure>
-      <para>The above are the default actions.  In addition, you can

-	or put scripts with those names, in the

-	after the regular extraction actions, and the
-	<filename>pre-build</filename> script will be executed before
-	the default build rules are done.  It is recommended that you
-	use <filename>Makefile</filename> targets if the actions are
-	simple enough, because it will be easier for someone to figure
-	out what kind of non-default action the port requires.</para>
-      <para>The default actions are done by the
-	<filename></filename> targets
-	<buildtarget>do-<replaceable>something</replaceable></buildtarget>.
-	For example, the commands to extract a port are in the target

-	target in your <filename>Makefile</filename>.</para>
-      <note>
-	<para>The <quote>main</quote> targets (e.g.,
-	  <buildtarget>extract</buildtarget>,
-	  <buildtarget>configure</buildtarget>, etc.) do nothing more
-	  than make sure all the stages up to that one are completed
-	  and call the real targets or scripts, and they are not
-	  intended to be changed.  If you want to fix the extraction,
-	  fix <buildtarget>do-extract</buildtarget>, but never ever
-	  change the way <buildtarget>extract</buildtarget>
-	  operates! Additionally, the target
-	  <buildtarget>post-deinstall</buildtarget> is invalid and
