  <title>Typography</title>

  <para>To make things easier to follow, there are a few typographical
  conventions used throughout this book. This section contains some
  examples of the typographical format found throughout Cross-Compiled
  Linux From Scratch.</para>

<screen role="nodump"><userinput>./configure --prefix=/usr</userinput></screen>

  <para>This form of text is designed to be typed exactly as seen unless
  otherwise noted in the surrounding text. It is also used in the
  explanation sections to identify which of the commands is being
  referenced.</para>

<screen><computeroutput>install-info: unknown option '--dir-file=/mnt/clfs/usr/info/dir'</computeroutput></screen>

  <para>This form of text (fixed-width text) shows screen output,
  probably as the result of commands issued.  This format is also used
  to show filenames, such as <filename>/etc/ld.so.conf</filename>.</para>

  <para><emphasis>Emphasis</emphasis></para>

  <para>This form of text is used for several purposes in the book.
  Its main purpose is to emphasize important points or items.</para>

  <para><ulink url="&clfs-root;"/></para>

  <para>This format is used for hyperlinks, both within the CLFS
  community and to external pages. It includes HOWTOs, download locations,
  and websites.</para>

<screen role="nodump"><userinput>cat &gt; ${CLFS}/etc/group &lt;&lt; "EOF"
<literal>root:x:0:
bin:x:1:
......</literal>
EOF</userinput></screen>

  <para>This format is used when creating configuration files. The first
  command tells the system to create the file
  <filename>${CLFS}/etc/group</filename> from whatever is typed on the
  following lines until the sequence end of file (EOF) is encountered.
  Therefore, this entire section is generally typed as seen.</para>

  <para><replaceable>[REPLACED TEXT]</replaceable></para>

  <para>This format is used to encapsulate text that is not to be typed
  as seen or copied-and-pasted.</para>

  <para><filename>passwd(5)</filename></para>

  <para>This format is used to refer to a specific manual page (hereinafter
  referred to simply as a <quote>man</quote> page). The number inside
  parentheses indicates a specific section inside of <command>man</command>.
  For example, <command>passwd</command> has two man pages. Per CLFS
  installation instructions, those two man pages will be located at
  <filename>/usr/share/man/man1/passwd.1</filename> and
  <filename>/usr/share/man/man5/passwd.5</filename>. Both man pages have
  different information in them. When the book uses
  <filename>passwd(5)</filename> it is specifically referring to
  <filename>/usr/share/man/man5/passwd.5</filename>.
  <command>man passwd</command> will print the first man page it finds
  that matches <quote>passwd</quote>, which will be
  <filename>/usr/share/man/man1/passwd.1</filename>. For this example,
  you will need to run <command>man 5 passwd</command> in order to read
  the specific page being referred to. It should be noted that most man
  pages do not have duplicate page names in different sections. Therefore,
  <command>man <replaceable>[program name]</replaceable></command> is
  generally sufficient.</para>
