buildroot.html: html code clean-up and other issues - Part2

The current DocType declaration was incorrect. It is neither xhtml strict nor
xhtml transitional. So, instead of dealing with that issue, converted it to
validated Html5.

Fixed white-space errors.
Removed validator html4.01 code.
Color corrected the code sections.
Removed redundant or useless html code.
Changed foo to libfoo, for consistency.
Changed page bookmarking to use header id's.
Re-flowed paragraphs to line break at 80 characters.
Re-formatted the code sections for consistency and correctness.
Kept all list items, headings, and href's on a single line (where possible).

-   <p>The Makefile begins on line 6 to 8 by metadata informations: the
-   version of the package (<code>LIBFOO_VERSION</code>), the name of
-   the tarball containing the package (<code>LIBFOO_SOURCE</code>) and
-   the Internet location at which the tarball can be downloaded
-   (<code>LIBFOO_SITE</code>). All variables must start with the same
-   prefix, <code>LIBFOO_</code> in this case. This prefix is always
-   the uppercased version of the package name (see below to understand
-   where the package name is defined).</p>
-
-   <p>On line 9, we specify that this package wants to install
-   something to the staging space. This is often needed for libraries
-   since they must install header files and other development files in
-   the staging space. This will ensure that the commands listed in the
-   <code>LIBFOO_INSTALL_STAGING_CMDS</code> variable will be
-   executed.</p>
-
-   <p>On line 10, we specify the list of dependencies this package
-   relies on. These dependencies are listed in terms of lower-case
-   package names, which can be packages for the target (without the
-   <code>host-</code> prefix) or packages for the host (with the
-   <code>host-</code>) prefix). Buildroot will ensure that all these
-   packages are built and installed <i>before</i> the current package
-   starts its configuration.</p>
-
-   <p>The rest of the Makefile defines what should be done at the
-   different steps of the package configuration, compilation and
-   installation. <code>LIBFOO_BUILD_CMDS</code> tells what steps
-   should be performed to build the
-   package. <code>LIBFOO_INSTALL_STAGING_CMDS</code> tells what steps
-   should be performed to install the package in the staging
-   space. <code>LIBFOO_INSTALL_TARGET_CMDS</code> tells what steps
-   should be performed to install the package in the target space.</p>
-
-   <p>All these steps rely on the <code>$(@D)</code> variable, which
-   contains the directory where the source code of the package has
-   been extracted.</p>
-
-   <p>Finally, on line 27, we call the <code>GENTARGETS</code> which
-   generates, according to the variables defined previously, all the
-   Makefile code necessary to make your package working.</p>
-
-   <h4><a name="generic-reference"></a>Makefile for generic packages :
-   reference</h4>
-
-   <p>The <code>GENTARGETS</code> macro takes three arguments:</p>
-
-   <ul>
-
-     <li>The first argument is the package directory prefix. If your
-     package is in <code>package/libfoo</code>, then the directory
-     prefix is <code>package</code>. If your package is in
-     <code>package/editors/foo</code>, then the directory prefix must
-     be <code>package/editors</code>.</li>
-
-     <li>The second argument is the lower-cased package name. It must
-     match the prefix of the variables in the <code>.mk</code> file
-     and must match the configuration option name in the
-     <code>Config.in</code> file. For example, if the package name is
-     <code>libfoo</code>, so the variables in the <code>.mk</code>
-     must start with <code>LIBFOO_</code> and the configuration option
-     in the <code>Config.in</code> file must be
-     <code>BR2_PACKAGE_LIBFOO</code>.</li>
-
-     <li>The third argument is optional. It can be used to tell if the
-     package if a target package (cross-compiled for the target) or a
-     host package (natively compiled for the host). If unspecified, it
-     is assumed that it is a target package. See below for
-     details.</li>
-
-   </ul>
-
-   <p>For a given package, in a single <code>.mk</code> file, it is
-   possible to call GENTARGETS twice, once to create the rules to
-   generate a target package and once to create the rules to generate
-   a host package:</p>

 $(eval $(call GENTARGETS,package,libfoo))
 $(eval $(call GENTARGETS,package,libfoo,host))
 </pre>
 
-   <p>This might be useful if the compilation of the target package
-   requires some tools to be installed on the host. If the package
-   name is <code>libfoo</code>, then the name of the package for the
-   target is also <code>libfoo</code>, while the name of the package
-   for the host is <code>host-libfoo</code>. These names should be
-   used in the DEPENDENCIES variables of other packages if they depend
-   on <code>libfoo</code> or <code>host-libfoo</code>.</p>
-
-   <p>The call to the <code>GENTARGETS</code> macro <b>must</b> be at
-   the end of the <code>.mk</code> file, after all variable
-   definitions.</p>
-
-   <p>For the target package, the <code>GENTARGETS</code> uses the
-   variables defined by the .mk file and prefixed by the uppercased
-   package name: <code>LIBFOO_*</code>. For the host package, it uses
-   the <code>HOST_LIBFOO_*</code>. For <i>some</i> variables, if the
-   <code>HOST_LIBFOO_</code> prefixed variable doesn't exist, the
-   package infrastructure uses the corresponding variable prefixed by
-   <code>LIBFOO_</code>. This is done for variables that are likely to
-   have the same value for both the target and host packages. See
-   below for details.</p>
-
-   <p>The list of variables that can be set in a <code>.mk</code> file
-   to give metadata informations is (assuming the package name is
-   <code>libfoo</code>) :</p>
-
-   <ul>
-
-     <li><code>LIBFOO_VERSION</code>, mandatory, must contain the
-     version of the package. Note that if
-     <code>HOST_LIBFOO_VERSION</code> doesn't exist, it is assumed to
-     be the same as <code>LIBFOO_VERSION</code>.<br/>Example:
-     <code>LIBFOO_VERSION=0.1.2</code></li>
-
-     <li><code>LIBFOO_SOURCE</code> may contain the name of the
-     tarball of the package. If <code>HOST_LIBFOO_SOURCE</code> is not
-     specified, it defaults to <code>LIBFOO_VERSION</code>. If none
-     are specified, then the value is assumed to be
-     <code>packagename-$(LIBFOO_VERSION).tar.gz</code>.<br/>Example:
-     <code>LIBFOO_SOURCE =
-     foobar-$(LIBFOO_VERSION).tar.bz2</code></li>
-
-     <li><code>LIBFOO_PATCH</code> may contain the name of a patch,
-     that will be downloaded from the same location as the tarball
-     indicated in <code>LIBFOO_SOURCE</code>. If
-     <code>HOST_LIBFOO_PATCH</code> is not specified, it defaults to
-     <code>LIBFOO_PATCH</code>. Also note that another mechanism is
-     available to patch a package: all files of the form
-     <code>packagename-packageversion-description.patch</code> present
-     in the package directory inside Buildroot will be applied to the
-     package after extraction.</li>
-
-     <li><code>LIBFOO_SITE</code> may contain the Internet location of
-     the tarball of the package. If <code>HOST_LIBFOO_SITE</code> is
-     not specified, it defaults to <code>LIBFOO_SITE</code>. If none
-     are specified, then the location is assumed to be
-     <code>http://$$(BR2_SOURCEFORGE_MIRROR).dl.sourceforge.net/sourceforge/packagename</code>.<br/>Example:
-     <code>LIBFOO_SITE=http://www.foosoftware.org/libfoo</code>.</li>
-
-     <li><code>LIBFOO_DEPENDENCIES</code> lists the dependencies (in
-     terms of package name) that are required for the current target
-     package to compile. These dependencies are guaranteed to be
-     compiled and installed before the configuration of the current
-     package starts. In a similar way,
-     <code>HOST_LIBFOO_DEPENDENCIES</code> lists the dependency for
-     the current host package.</li>
-
-     <li><code>LIBFOO_INSTALL_STAGING</code> can be set to
-     <code>YES</code> or <code>NO</code> (default). If set to
-     <code>YES</code>, then the commands in the
-     <code>LIBFOO_INSTALL_STAGING_CMDS</code> variables are executed
-     to install the package into the staging directory.</p>
-
-     <li><code>LIBFOO_INSTALL_TARGET</code> can be set to
-     <code>YES</code> (default) or <code>NO</code>. If set to
-     <code>YES</code>, then the commands in the
-     <code>LIBFOO_INSTALL_TARGET_CMDS</code> variables are executed
-     to install the package into the target directory.</p>
-
-     </ul>
-
-     <p>The recommended way to define these variables is to use the
-     following syntax:</p>
+    <p>This might be useful if the compilation of the target package 
+    requires some tools to be installed on the host. If the package name is 
+    <code>libfoo</code>, then the name of the package for the target is also 
+    <code>libfoo</code>, while the name of the package for the host is 
+    <code>host-libfoo</code>. These names should be used in the DEPENDENCIES 
+    variables of other packages if they depend on <code>libfoo</code> or 
+    <code>host-libfoo</code>.</p>
+
+    <p>The call to the <code>GENTARGETS</code> macro <b>must</b> be at the 
+    end of the <code>.mk</code> file, after all variable definitions.</p>
+
+    <p>For the target package, the <code>GENTARGETS</code> uses the 
+    variables defined by the .mk file and prefixed by the uppercased package 
+    name: <code>LIBFOO_*</code>. For the host package, it uses the 
+    <code>HOST_LIBFOO_*</code>. For <i>some</i> variables, if the 
+    <code>HOST_LIBFOO_</code> prefixed variable doesn't exist, the package 
+    infrastructure uses the corresponding variable prefixed by 
+    <code>LIBFOO_</code>. This is done for variables that are likely to have 
+    the same value for both the target and host packages. See below for 
+    details.</p>
+
+    <p>The list of variables that can be set in a <code>.mk</code> file to 
+    give metadata informations is (assuming the package name is 
+    <code>libfoo</code>) :</p>
+
+    <ul>
+      <li><code>LIBFOO_VERSION</code>, mandatory, must contain the version 
+      of the package. Note that if <code>HOST_LIBFOO_VERSION</code> doesn't 
+      exist, it is assumed to be the same as <code>LIBFOO_VERSION</code>.
+      <br/>Example: <code>LIBFOO_VERSION=0.1.2</code></li>
+
+      <li><code>LIBFOO_SOURCE</code> may contain the name of the tarball of 
+      the package. If <code>HOST_LIBFOO_SOURCE</code> is not specified, it 
+      defaults to <code>LIBFOO_VERSION</code>. If none are specified, then 
+      the value is assumed to be 
+      <code>packagename-$(LIBFOO_VERSION).tar.gz</code>.<br/>Example: 
+      <code>LIBFOO_SOURCE = foobar-$(LIBFOO_VERSION).tar.bz2</code></li>
+
+      <li><code>LIBFOO_PATCH</code> may contain the name of a patch, that 
+      will be downloaded from the same location as the tarball indicated in 
+      <code>LIBFOO_SOURCE</code>. If <code>HOST_LIBFOO_PATCH</code> is not 
+      specified, it defaults to <code>LIBFOO_PATCH</code>. Also note that 
+      another mechanism is available to patch a package: all files of the 
+      form <code>packagename-packageversion-description.patch</code> present 
+      in the package directory inside Buildroot will be applied to the 
+      package after extraction.</li>
+
+      <li><code>LIBFOO_SITE</code> may contain the Internet location of the 
+      tarball of the package. If <code>HOST_LIBFOO_SITE</code> is not 
+      specified, it defaults to <code>LIBFOO_SITE</code>. If none are 
+      specified, then the location is assumed to be 
+      <code>http://$$(BR2_SOURCEFORGE_MIRROR).dl.sourceforge.net/sourceforge/packagename</code>.
+      <br/>Example: 
+      <code>LIBFOO_SITE=http://www.foosoftware.org/libfoo</code>.</li>
+
+      <li><code>LIBFOO_DEPENDENCIES</code> lists the dependencies (in terms 
+      of package name) that are required for the current target package to 
+      compile. These dependencies are guaranteed to be compiled and 
+      installed before the configuration of the current package starts. In a 
+      similar way, <code>HOST_LIBFOO_DEPENDENCIES</code> lists the 
+      dependency for the current host package.</li>
+
+      <li><code>LIBFOO_INSTALL_STAGING</code> can be set to <code>YES</code> 
+      or <code>NO</code> (default). If set to <code>YES</code>, then the 
+      commands in the <code>LIBFOO_INSTALL_STAGING_CMDS</code> variables are 
+      executed to install the package into the staging directory.</li>
+
+      <li><code>LIBFOO_INSTALL_TARGET</code> can be set to <code>YES</code> 
+      (default) or <code>NO</code>. If set to <code>YES</code>, then the 
+      commands in the <code>LIBFOO_INSTALL_TARGET_CMDS</code> variables are 
+      executed to install the package into the target directory.</li> </ul>
+
+    <p>The recommended way to define these variables is to use the following 
+    syntax:</p>

-    <p>On line 10, we tell Buildroot to install the package to the
-    staging directory. The staging directory, located in

-    default, packages are not installed to the staging directory,
-    since usually, only libraries need to be installed in the staging
-    directory: their development files are needed to compile other
-    libraries or applications depending on them. Also by default, when
-    staging installation is enabled, packages are installed in this
-    location using the <code>make install</code> command.</p>

-    <p>Finally, on line line 14, we invoke the

-    rules that actually allows the package to be built.</p>
-
-    <h4><a name="autotools-reference"></a>Makefile for autotools
-    packages : reference</h4>
-
-    <p>The main macro of the autotools package infrastructure is
-    <code>AUTOTARGETS</code>. It has the same number of arguments and
-    the same semantic as the <code>GENTARGETS</code> macro, which is
-    the main macro of the generic package infrastructure. For
-    autotools packages, the ability to have target and host packages
-    is also available (and is actually widely used).</p>
-
-    <p>Just like the generic infrastructure, the autotools
-    infrastructure works by defining a number of variables before
-    calling the <code>AUTOTARGETS</code> macro.</p>
-
-    <p>First, all the package meta-information variables that exist in
-    the generic infrastructure also exist in the autotools
-    infrastructure: <code>LIBFOO_VERSION</code>,
-    <code>LIBFOO_SOURCE</code>, <code>LIBFOO_PATCH</code>,
-    <code>LIBFOO_SITE</code>, <code>LIBFOO_SUBDIR</code>,
-    <code>LIBFOO_DEPENDENCIES</code>,
-    <code>LIBFOO_INSTALL_STAGING</code>,
-    <code>LIBFOO_INSTALL_TARGET</code>.</p>
-
-    <p>A few additional variables, specific to the autotools
-    infrastructure, can also be defined. Many of them are only useful
-    in very specific cases, typical packages will therefore only use a
-    few of them.</p>
+    <p>Finally, on line line 14, we invoke the <code>AUTOTARGETS</code> 
+    macro that generates all the Makefile rules that actually allows the 
+    package to be built.</p>

+    <h4 id="autotools-reference">Makefile for autotools packages : reference</h4>
 
-      <li><code>LIBFOO_SUBDIR</code> may contain the name of a
-      subdirectory inside the package that contains the configure
-      script. This is useful, if for example, the main configure
-      script is not at the root of the tree extracted by the
-      tarball. If <code>HOST_LIBFOO_SUBDIR</code> is not specified, it
-      defaults to <code>LIBFOO_SUBDIR</code>.</li>
-
-      <li><code>LIBFOO_CONF_ENV</code>, to specify additional
-      environment variables to pass to the configure script. By
-      default, empty.</li>
-
-      <li><code>LIBFOO_CONF_OPT</code>, to specify additional
-      configure options to pass to the configure script. By default,
-      empty.</li>
-
-      <li><code>LIBFOO_MAKE</code>, to specify an
-      alternate <code>make</code> command. This is typically useful
-      when parallel make it enabled in the configuration
-      (using <code>BR2_JLEVEL</code>) but that this feature should be
-      disabled for the given package, for one reason or another. By
-      default, set to <code>$(MAKE)</code>. If parallel building is
-      not supported by the package, then it should
-      do <code>LIBFOO_MAKE=$(MAKE1)</code>.</li>
-
-      <li><code>LIBFOO_MAKE_ENV</code>, to specify additional
-      environment variables to pass to make in the build step. These
-      are passed before the <code>make</code> command. By default,
-      empty.</li>
-
-      <li><code>LIBFOO_MAKE_OPT</code>, to specify additional
-      variables to pass to make in the build step. These are passed
-      after the <code>make</code> command. By default, empty.</li>
-
-      <li><code>LIBFOO_AUTORECONF</code>, tells whether the package
-      should be autoreconfigured or not (i.e, if the configure script
-      and Makefile.in files should be re-generated by re-running
-      autoconf, automake, libtool, etc.). Valid values
-      are <code>YES</code> and <code>NO</code>. By default, the value
-      is <code>NO</code></li>
-
-      <li><code>LIBFOO_AUTORECONF_OPT</code> to specify additional
-      options passed to the <i>autoreconf</i> program
-      if <code>LIBFOO_AUTORECONF=YES</code>. By default, empty.</li>
-
-      <li><code>LIBFOO_LIBTOOL_PATCH</code> tells whether the
-      Buildroot patch to fix libtool cross-compilation issues should
-      be applied or not. Valid values are <code>YES</code>
-      and <code>NO</code>. By default, the value
-      is <code>YES</code></li>
-
-      <li><code>LIBFOO_USE_CONFIG_CACHE</code> tells whether the
-      configure script should really on a cache file that caches test
-      results from previous configure script. Usually, this variable
-      should be left to its default value. Only for specific packages
-      having issues with the configure cache can set this variable to
-      the <code>NO</code> value (but this is more a work-around than a
-      really fix)</li>
-
-      <li><code>LIBFOO_INSTALL_STAGING_OPT</code> contains the make
-      options used to install the package to the staging directory. By
-      default, the value is <code>DESTDIR=$$(STAGING_DIR)
-      install</code>, which is correct for most autotools packages. It
-      is still possible to override it.</li>
-
-      <li><code>LIBFOO_INSTALL_TARGET_OPT</code> contains the make
-      options used to install the package to the target directory. By
-      default, the value is <code>DESTDIR=$$(TARGET_DIR)
-      install-strip</code> if <code>BR2_ENABLE_DEBUG</code> is not
-      set, and <code>DESTDIR=$$(TARGET_DIR) install-exec</code>
-      if <code>BR2_ENABLE_DEBUG</code> is set. These default values
-      are correct for most autotools packages, but it is still
-      possible to override them if needed.</li>
-
-      <li><code>LIBFOO_CLEAN_OPT</code> contains the make options used
-      to clean the package. By default, the value
-      is <code>clean</code>.</li>
-
-      <li><code>LIBFOO_UNINSTALL_STAGING_OPT</code>, contains the make
-      options used to uninstall the package from the staging
-      directory. By default, the value is
-      <code>DESTDIR=$$(STAGING_DIR) uninstall</code>.</li>
-
-      <li><code>LIBFOO_UNINSTALL_TARGET_OPT</code>, contains the make
-      options used to uninstall the package from the target
-      directory. By default, the value is
-      <code>DESTDIR=$$(TARGET_DIR) uninstall</code>.</li>
+    <p>The main macro of the autotools package infrastructure is 
+    <code>AUTOTARGETS</code>. It has the same number of arguments and the 
+    same semantic as the <code>GENTARGETS</code> macro, which is the main 
+    macro of the generic package infrastructure. For autotools packages, the 
+    ability to have target and host packages is also available (and is 
+    actually widely used).</p>
 
-    </ul>
+    <p>Just like the generic infrastructure, the autotools infrastructure 
+    works by defining a number of variables before calling the 
+    <code>AUTOTARGETS</code> macro.</p>
 
-    <p>With the autotools infrastructure, all the steps required to
-    build and install the packages are already defined, and they
-    generally work well for most autotools-based packages. However,
-    when required, it is still possible to customize what is done in
-    particular step:</p>
+    <p>First, all the package meta-information variables that exist in the 
+    generic infrastructure also exist in the autotools infrastructure: 
+    <code>LIBFOO_VERSION</code>, <code>LIBFOO_SOURCE</code>, 
+    <code>LIBFOO_PATCH</code>, <code>LIBFOO_SITE</code>, 
+    <code>LIBFOO_SUBDIR</code>, <code>LIBFOO_DEPENDENCIES</code>, 
+    <code>LIBFOO_INSTALL_STAGING</code>, <code>LIBFOO_INSTALL_TARGET</code>.</p>
 
-    <ul>
+    <p>A few additional variables, specific to the autotools infrastructure, 
+    can also be defined. Many of them are only useful in very specific 
+    cases, typical packages will therefore only use a few of them.</p>
 
-      <li>By adding a post-operation hook (after extract, patch,
-      configure, build or install). See the reference documentation of
-      the generic infrastructure for details.</li>
+    <ul>
+      <li><code>LIBFOO_SUBDIR</code> may contain the name of a subdirectory 
+      inside the package that contains the configure script. This is useful, 
+      if for example, the main configure script is not at the root of the 
+      tree extracted by the tarball. If <code>HOST_LIBFOO_SUBDIR</code> is 
+      not specified, it defaults to <code>LIBFOO_SUBDIR</code>.</li>
+
+      <li><code>LIBFOO_CONF_ENV</code>, to specify additional environment 
+      variables to pass to the configure script. By default, empty.</li>
+
+      <li><code>LIBFOO_CONF_OPT</code>, to specify additional configure 
+      options to pass to the configure script. By default, empty.</li>
+
+      <li><code>LIBFOO_MAKE</code>, to specify an alternate <code>make</code>
+      command. This is typically useful when parallel make it enabled in 
+      the configuration (using <code>BR2_JLEVEL</code>) but that this

+      <code>make</code> command. By default, empty.</li>
+
+      <li><code>LIBFOO_AUTORECONF</code>, tells whether the package should 
+      be autoreconfigured or not (i.e, if the configure script and 
+      Makefile.in files should be re-generated by re-running autoconf,

+      <code>LIBFOO_AUTORECONF=YES</code>. By default, empty.</li>
+
+      <li><code>LIBFOO_LIBTOOL_PATCH</code> tells whether the Buildroot 
+      patch to fix libtool cross-compilation issues should be applied or 
+      not. Valid values are <code>YES</code> and <code>NO</code>. By 
+      default, the value is <code>YES</code></li>

+      its default value. Only for specific packages having issues with the 
+      configure cache can set this variable to the <code>NO</code> value 
+      (but this is more a work-around than a really fix)</li>
+
+      <li><code>LIBFOO_INSTALL_STAGING_OPT</code> contains the make options 
+      used to install the package to the staging directory. By default, the 
+      value is <code>DESTDIR=$$(STAGING_DIR) install</code>, which is 
+      correct for most autotools packages. It is still possible to override 
+      it.</li>
+
+      <li><code>LIBFOO_INSTALL_TARGET_OPT</code> contains the make options 
+      used to install the package to the target directory. By default, the 
+      value is <code>DESTDIR=$$(TARGET_DIR) install-strip</code> if 
+      <code>BR2_ENABLE_DEBUG</code> is not set, and 
+      <code>DESTDIR=$$(TARGET_DIR) install-exec</code> if 
+      <code>BR2_ENABLE_DEBUG</code> is set. These default values are correct 
+      for most autotools packages, but it is still possible to override them

+    </ul>
 
-      <li>By overriding one of the steps. For example, even if the
-      autotools infrastructure is used, if the package
-      <code>.mk</code> defines its own
-      <code>LIBFOO_CONFIGURE_CMDS</code> variable, it will be used
-      instead of the default autotools one. However, using this method
-      should be restricted to very specific cases. Do not use it in
-      the general case.</li>
