<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 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>
<para>In some cases, a logical line is extended to two or more physical lines
with a backslash at the end of the line.</para>
<screen role="nodump"><userinput>CC="gcc -B/usr/bin/" ../binutils-2.18/configure \
--prefix=/tools --disable-nls --disable-werror</userinput></screen>
<para>Note that the backslash must be followed by an immediate return. Other
whitespace characters like spaces or tab characters will create incorrect
results.</para>
<screen><computeroutput>install-info: unknown option '--dir-file=/mnt/lfs/usr/info/dir'</computeroutput></screen>
<para>This form of text (fixed-width text) shows screen output, usually as
the result of commands issued. This format is also used to show filenames,
such as <filename>/etc/ld.so.conf</filename>.</para>
<note>
<para>Please configure your browser to display fixed-width text with
a good monospaced font, with which you can distinguish the glyphs of
<literal>Il1</literal> or <literal>O0</literal> clearly.</para>
</note>
<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="&lfs-root;"/></para>
<para>This format is used for hyperlinks both within the LFS community and to
external pages. It includes HOWTOs, download locations, and websites.</para>
<screen role="nodump"><userinput>cat > $LFS/etc/group << "EOF"
<literal>root:x:0:
bin:x:1:
......</literal>
EOF</userinput></screen>
<para>This format is used when creating configuration files. The first command
tells the system to create the file <filename>$LFS/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 for copy-and-paste operations.</para>
<para><replaceable>[OPTIONAL TEXT]</replaceable></para>
<para>This format is used to encapsulate text that is optional.</para>
<para><filename>passwd(5)</filename></para>
<para>This format is used to refer to a specific manual (man) page. The number inside parentheses
indicates a specific section inside the manuals. For example,
<command>passwd</command> has two man pages. Per LFS 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>. 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 page
being specified. Note 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>
