<title>Installation of Man</title>

<para>We'll make three adjustments to the sources of Man.</para>
 
<para>The first patch comments out the "MANPATH /usr/man" line in the
<filename>man.conf</filename> file to prevent redundant results when using
 programs such as <userinput>whatis</userinput>:</para>

<para><screen><userinput>patch -Np1 -i ../man-&man-manpath-patch-version;-manpath.patch</userinput></screen></para>

<para>The second patch adds the <emphasis>-R</emphasis> option to the
<emphasis>PAGER</emphasis> variable so that escape sequences are
handled properly:</para>

<para><screen><userinput>patch -Np1 -i ../man-&man-pager-patch-version;-pager.patch</userinput></screen></para>

<para>The third and last patch prevents a problem when man pages not formatted
with more than 80 columns are used in conjunction with recent releases of
<userinput>groff</userinput>:</para>

<para><screen><userinput>patch -Np1 -i ../man-&man-80cols-patch-version;-80cols.patch</userinput></screen></para>

<para>The paths to some programs are hard-wired into Man's executables.
Unfortunately, the configuration script picks the last location in PATH
rather than the first place a program is found. By appending
<emphasis>/usr/bin:/bin</emphasis> to PATH for the
<userinput>./configure</userinput> command, we ensure that Man doesn't
use the programs in the <filename class="directory">/tools</filename>
directory.</para>

<para>Now prepare Man for compilation:</para>

<para><screen><userinput>PATH=$PATH:/usr/bin:/bin ./configure -default -confdir=/etc</userinput></screen></para>

<para>Compile the package:</para>

<para><screen><userinput>make</userinput></screen></para>

<para>And install it:</para>

<para><screen><userinput>make install</userinput></screen></para>

<note><para>If you wish to disable SGR escape sequences, you should
edit the man.conf file and add the <userinput>-c</userinput> argument
to nroff.</para></note>

<para>You may want to also take a look at the BLFS book which deals with 
formatting and compression issues for man pages.</para>
