          if using a locale with a multibyte character set. This switch is

    However, this test suite outputs a lot of binary data to the

    <command>vi</command>. Create a symlink to permit execution of
    <command>vim</command> when users habitually enter <command>vi</command>

<para os="n">By default, Vim's documentation is installed in

    <para os="p">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 the CBLFS book at <ulink

    <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; /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>
