<h3>Standard Libraries</h3>
<p>
<b>nhc98</b> supports all the standard libraries from the official
<a href="http://www.haskell.org/onlinelibrary/_._.html">
<em>Haskell '98 Library Report</em></a>. Here is a summary of
the status of each.

<h3>Extension libraries</h3>
<p>
Many of the standard hierarchical libraries are provided in
<b>nhc98</b>. To use these, you must add the compile-time
option <em>-package pkg</em>, where <em>pkg</em> is the name
of the package. See
<a href="http://www.haskell.org/ghc/docs/latest/html/libraries/index.html">
here</a> for ghc's documentation of many of these.
<p>
Packages supplied with nhc98-1.20 are:
base, Cabal, directory, filepath, fps, haskell-src, HaXml,
html, HUnit, old-locale, old-time, parsec, polyparse, pretty,
process, QuickCheck, random, xhtml
