<para>The <acronym>LFS</acronym> book installs
<application>vim</application> as its editor.  At this point we should
state that there are a <emphasis>lot</emphasis> of different editors out
there including <application>emacs</application>,
<application>nano</application>, <application>joe</application> and many 
more.  Anyone who has been around the Internet (especially usenet) for a 
short time will certainly have observed at least one flame war, usually 
involving <application>vim</application> and
<application>emacs</application> users!</para>

<para>The <acronym>LFS</acronym> book gives a basic <filename>vimrc
</filename> file.  Here, we attempt to enhance this file.  At startup,
<command>vim</command> reads <filename>/etc/vimrc</filename> and 
<filename>~/.vimrc</filename> (i.e., the global
<filename>vimrc</filename> and the user-specific one.).  Note that this is
only true if you compiled <application>vim</application> using
<acronym>LFS</acronym>-3.1 onwards.  Prior to this,
the global <filename>vimrc</filename> was <filename>/usr/share/vim/vimrc
</filename>.</para>

<para>Here is a slightly expanded <filename>vimrc</filename> that you can 
put in <filename>/etc/vimrc</filename> to provide global effect. Of course, if
you put it into <filename>/etc/skel/.vimrc</filename> instead, it will
be made available to users you add to the system later. You can also copy
the file from <filename>/etc/skel/.vimrc</filename> to
<filename>/etc/vimrc</filename> and the home directory of users already
on the system, like root. Be sure to set permissions, owner and group if
you do copy anything directly from <filename>/etc/skel</filename>.</para>

<para>A <acronym>FAQ</acronym> on the lfs mailing lists regards the 
comment tags in <filename>vimrc</filename>.  Note that they are " instead 
of the more usual # or //.  This is correct, the syntax for <filename>vimrc
</filename> is slightly unusual.</para>

<para>We'll run through a quick explanation of what each of the
options in this example file means here:</para>
<itemizedlist>

<listitem><para><userinput>set bs=2</userinput> : This influences the behavior 
of the backspace option.  It is fairly complex so see <userinput>:help 'bs'
</userinput> for more details.</para></listitem>

<listitem><para><userinput>set columns=72</userinput> : This simply sets the 
number of columns used on the screen.</para></listitem>

<listitem><para><userinput>set background=dark</userinput> : This tells
<command>vim</command> to use colors which look good on a dark 
background.</para></listitem>

<listitem><para><userinput>syntax on</userinput> : Enables
<command>vim</command>'s syntax highlighting.</para></listitem>

<listitem><para><userinput>set ruler</userinput> : This makes <command>vim
</command> show the current row and column at the bottom right of
the screen.</para></listitem>


</itemizedlist>

<para>More information on the <emphasis>many</emphasis> <command>vim</command> 
options can be found by reading the help inside <command>vim</command> itself.  
Do this by typing <command>:</command><userinput>help</userinput> in 
<command>vim</command> to get the general help, or by typing <command>:
</command><userinput>help usr_toc.txt</userinput> to view 
the User Manual Table of Contents.</para>
