|
|
<P>We mentioned above that using underlining as a form of text emphasis
|
|
presents special problems. Actually, TeX has no problem underlining
|
|
text, because it is a convention of mathematical typesetting. In
|
|
LaTeX, you can underline words with the command:
|
|
<PRE>
|
|
\underline{text to be underlined}
|
|
</PRE>
|
|
|
|
The problem is that underlining will not break across lines, and, in
|
|
some circumstances, underlining can be uneven. However, there is a
|
|
LaTeX macro package, ready-made, that makes underlining the default
|
|
mode of text emphasis. It's called <CODE>ulem.sty</CODE>, and is one of
|
|
the many contributed LaTeX packages that are freely available via the
|
|
Internet.
|
|
<P>To use <CODE>ulem.sty</CODE>, include the command:
|
|
<PRE>
|
|
\usepackage{ulem}
|
|
</PRE>
|
|
|
|
in the document preamble.
|
|
<P>The packages which are available for LaTeX include:
|
|
<DL>
|
|
<DT><B>ifthen </B><DD><P>Include conditional statements in your documents.
|
|
<DT><B>initials </B><DD><P>Defines a font for initial dropped capitals.
|
|
<DT><B>sanskrit </B><DD><P>Font and preprocessor for producing documents in Sanskrit.
|
|
<DT><B>recipe </B><DD><P>A LaTeX2e class to typeset recipes.
|
|
<DT><B>refman </B><DD><P>Variant report and article styles.
|
|
</DL>
|
|
<P>To make the path given in the Catalogue into a fully-qualified URL,
|
|
concatenate the path to the host name URL and top-level path of the CTAN
|
|
archive you wish to contact. For example, the top-level CTAN
|
|
directory of the site
|
|
<A HREF="ftp://ftp.tex.ac.uk">ftp.tex.ac.uk</A> is <CODE>ctan/tex-archive</CODE>. The complete
|
|
URL of the directory of the <B>refman</B> package would be:
|
|
<PRE>
|
|
ftp://ftp.tex.ac.uk/ctan/tex-archive/ +
|
|
macros/latex/contrib/supported/refman =
|
|
|
|
ftp://ftp.tex.ac.uk/ctan/tex-archive/macros/latex/contrib/supported/refman/
|
|
</PRE>
|
|
|
|
Some packages have more than one file, so only the path to the
|
|
package's directory is given.
|
|
<P>When you have the URL in hand, you can retrieve the package from one
|
|
of the CTAN archive sites listed in section
|
|
<A HREF="TeTeX-HOWTO-8.html#ctan-list">Appendix A</A>. You can download a complete list of the archive's
|
|
contents as the file <CODE>FILES.byname</CODE>, in the archive's top-level
|
|
directory. You can also search the archive on line for a keyword with
|
|
the <CODE>ftp</CODE> command
|
|
<PRE>
|
|
quote site index <keyword>
|
|
</PRE>
