          <para>This optional but highly recommended switch enables support

    <para os="k">Many users are accustomed to using <command>vi</command>
    instead of <command>vim</command>. Some programs, such as
    <command>vigr</command> and <command>vipw</command>, also use
    <command>vi</command>. Create a symlink to permit execution of
    <command>vim</command> when users habitually enter <command>vi</command>
    and allow programs that use <command>vi</command> to work:</para>

<screen os="l"><userinput>ln -sfv vim ${CLFS}/usr/bin/vi</userinput></screen>

<para os="m">By default, Vim's documentation is installed in
<filename class="directory">/usr/share/vim</filename>.  The following symlink
allows the documentation to be accessed via
<filename class="directory">/usr/share/doc/vim-&vim-version;</filename>, making
it consistent with the location of documentation for other packages:</para>

<screen os="n"><userinput>ln -sfnv ../vim/vim&vim-version2;/doc ${CLFS}/usr/share/doc/vim-&vim-version;</userinput></screen>

    <para os="o">If an X Window System is going to be installed on the CLFS
    system, you may want to recompile Vim after installing X. Vim
    comes with a GUI version of the editor that requires X and some
    additional libraries to be installed. For more information, refer to the
    Vim documentation and the Vim installation page in CBLFS at <ulink
   url="&cblfs-root;index.php/Vim"/>.</para>

    </indexterm>

    <para>By default, <command>vim</command> runs in vi-incompatible mode.
    This may be new to users who have used other editors in the past. The
    <quote>nocompatible</quote> setting is included below to highlight the
    fact that a new behavior is being used. It also reminds those who would
    change to <quote>compatible</quote> mode that it should be the first
    setting in the configuration file. This is necessary because it changes
    other settings, and overrides must come after this setting. Create a
    default <command>vim</command> configuration file by running the
    following:</para>

<screen><userinput>cat &gt; ${CLFS}/etc/vimrc &lt;&lt; "EOF"
<literal>" Begin /etc/vimrc

set nocompatible
set backspace=2
syntax on
if (&amp;term == "iterm") || (&amp;term == "putty")
  set background=dark
endif

" End /etc/vimrc</literal>
EOF</userinput></screen>


    <para>The <parameter>set nocompatible</parameter> makes
    <command>vim</command> behave in a more useful way (the default) than
    the vi-compatible manner. Remove the <quote>no</quote> to keep the
    old <command>vi</command> behavior. The <parameter>set
    backspace=2</parameter> allows backspacing over line breaks,
    autoindents, and the start of insert. The <parameter>syntax
    on</parameter> enables vim's syntax highlighting. Finally, the
    <emphasis>if</emphasis> statement with the <parameter>set
    background=dark</parameter> corrects <command>vim</command>'s guess
    about the background color of some terminal emulators. This gives the
    highlighting a better color scheme for use on the black background of
    these programs.</para>

    <para>Documentation for other available options can be obtained by
    running the following command:</para>
