-<h2>Spans: Emacs and XEmacs compatibility library for overlays/extents</h2>
-
-<p>
-<i>Spans</i> are an abstraction of XEmacs <i>extents</i> used to help
-bridge the gulf between GNU Emacs and XEmacs. In GNU Emacs, spans are
-implemented using <i>overlays</i>.
-</p>
-<p>
-The library consists of three Emacs lisp files,
-<ul>
-<li><a href="ProofGeneral-latest/generic/span-extent.el">span-extent.el</a>
-</li>
-<li><a href="ProofGeneral-latest/generic/span-overlay.el">span-overlay.el</a>
-</li>
-<li><a href="ProofGeneral-latest/generic/span.el">span.el</a>
-(which simply loads one of the above)
-</li>
-</ul>
-which implement a common interface for overlays/extents.
-This library was originally implemented by Healfdene Goguen.
-</p>
-<p>
-See the files for further documentation, and
-<a href="htmlshow.php?title=Proof+General+adapting+manual&file=ProofGeneral%2Fdoc%2FPG-adapting_13.html#SEC40">section 12.1</a>
-of the <a href="adaptingman">Proof General adapting manual</a>
-for more details.

-<h2>Docstring magic: Elisp documentation to TeXinfo extraction</h2>
-
-<p>
-This package generates <a
-href="http://www.gnu.org/directory/texinfo.html">Texinfo</a> source
-fragments from Emacs
-<!-- WARNING: next URL subject to change with elisp ref man changes!! -->
-<a href="http://www.gnu.org/manual/elisp/html_node/elisp_374.html#SEC374">documentation strings</a> which are embedded in Emacs lisp source and the
-running interpreter. This avoids documenting functions
-and variables in more than one place, and automatically adds Texinfo
-markup to docstrings. It's a bit like <tt>javadoc</tt> for Emacs
-Lisp, except that you must write a skeleton <tt>texi</tt> file which
-contains magic comments mentioning the function or variable names you
-want documented. </p> <p> The package consists of one file: <ul>
-<li><a
-href="ProofGeneral-latest/generic/texi-docstring-magic.el">texi-docstring-magic.el</a></li>
-</ul> which contains documentation and usage hints. For an extensive
-example of it's use, see the <a
-href="ProofGeneral-latest/doc/PG-adapting.texi">source</a> for the <a
-href="adaptingman">PG adapting manual</a>. </p>
