-<h3>Typesetting URLs</h3>
-<p/>URLs tend to be very long, and contain characters that would
-naturally prevent them being hyphenated even if they weren&#8217;t typically
-set in <code>\</code><code>ttfamily</code>, verbatim. Therefore, without special treatment,
-they often produce wildly overfull <code>\</code><code>hbox</code>es, and their typeset
-representation is awful.
-<p/>There are three packages that help solve this problem:
-<ul>
-<li> The <i>path</i> package, which defines a <code>\</code><code>path</code> command.
- The command defines each potential break character as a
- <code>\</code><code>discretionary</code>, and offers the user the opportunity of
- specifying a personal list of potential break characters. Its chief
- disadvantage is fragility in LaTeX moving arguments. The
-
- <a href="FAQ-eplain.html">Eplain macros</a> &#8212; define a similar <code>\</code><code>path</code> command.
-<p/> <i>Path</i>, though it works in simple situations, makes no
- attempt to work with LaTeX (it is irremediably fragile). Despite
- its long and honourable history, it is no longer recommended for
- LaTeX use.
-<li> The <i>url</i> package, which defines an <code>\</code><code>url</code> command
- (among others, including its own <code>\</code><code>path</code> command). The command
- gives each potential break character a maths-mode &#8216;personality&#8217;, and
- then sets the URL itself (in the user&#8217;s choice of font) in
- maths mode. It can produce (LaTeX-style) &#8216;robust&#8217; commands
-
- (see <a href="FAQ-protect.html">use of <code>\</code><code>protect</code></a>) for use
- within moving arguments.
-<p/> The package ordinarily ignores spaces in the URL, but
- unfortunately URLs that contain spaces do exist; to typeset
- them, call the package with the <code>obeyspaces</code> option. Two
- other useful options allow line breaks in the URL in places
- where they are ordinarily suppressed to avoid confusion:
- <code>spaces</code> to allow breaks at spaces (note, this requires
- <code>obeyspaces</code> as well, and <code>hyphens</code> to allow
- breaks after hyphens. (Note that the package <em>never</em> does
- &#8220;ordinary&#8221; hyphenation of names inside an URL.)
-<p/> It is possible to use the <i>url</i> package in Plain TeX,
- with the assistance of the <i>miniltx</i> package (which was
- originally developed for using the LaTeX graphics package in
- Plain TeX). A small patch is also necessary: the required
- sequence is therefore:
-
-<pre>
-\input miniltx
-\expandafter\def\expandafter\+\expandafter{\+}
-\input url.sty
-</pre>
-<li> The <i>hyperref</i> package, which uses the typesetting code
- of <i>url</i>, in a context where the typeset text forms the
- anchor of a link.
-</ul>
-<p/>The author of this answer prefers the (rather newer) <i>url</i>
-package (directly or indirectly); both <i>path</i> and
-<i>url</i> work well with Plain TeX (though of course, the fancy
-LaTeX facilities of <i>url</i> don&#8217;t have much place there).
-(<i>hyperref</i> isn&#8217;t available in a version for use with Plain TeX.)
-<p/>Note that neither <code>\</code><code>path</code> (from package <i>path</i>) nor <code>\</code><code>url</code> (from
-package <i>url</i>) is robust (in the LaTeX sense). If you need
-a URL to go in a moving argument, you need the command
-<code>\</code><code>urldef</code> from the <i>url</i> package. So one might write:
-<blockquote>
-<pre>
-\urldef\faqhome\url{http://www.tex.ac.uk/faq}
-</pre>
-</blockquote><p>
-after which, <code>\</code><code>faqhome</code> is robust.
-<p/>Documentation of both package <i>path</i> and package <i>url</i>
-is in the package files.
