26 |
|

27 | <para>The first is a patch which allows Man to work better with recent releases
|

28 | of Groff. In particular, man pages will now display using the full terminal
|
---|
29 | width instead of being limited to 80 characters:</para>

32 |
|
---|
33 | <para>The second is a sed substitution to add the <emphasis>-R</emphasis>
|
---|
34 | switch to the <emphasis>PAGER</emphasis> variable so that escape sequences are
|

35 | properly handled by Less:</para>
|

37 | <screen><userinput>sed -i 's/-is/&R/' configure</userinput></screen>
|
---|
38 |
|
---|
39 | <para>The third is also a sed substitution to comment out the <quote>MANPATH
|
---|
40 | /usr/man</quote> line in the <filename>man.conf</filename> file to prevent
|
---|
41 | redundant results when using programs such as <command>whatis</command>:</para>

51 | <itemizedlist>
|
---|
52 | <listitem><para><userinput>-default</userinput>: This tells the configure script
|
---|
53 | to select a sensible set of default options. For example: only English man
|
---|
54 | pages, no message catalogs, man not suid, handle compressed man pages, compress
|
---|
55 | cat pages, create cat pages whenever the appropriate directory exists, follow
|

|

57 | exists).</para></listitem>

58 |

59 | <listitem><para><userinput>-confdir=/etc</userinput>: This tells the

74 | to NROFF.</para></note>
