<h2><a name="unpack">GUnzip/BUnzip2</a></h2>
<h3>Description</h3>
<p>Expands a file packed using GZip or BZip2.</p>
<p>If <i>dest</i> is a directory the name of the destination file is
the same as <i>src</i> (with the ".gz" or ".bz2"
extension removed if present). If <i>dest</i> is omitted, the parent
dir of <i>src</i> is taken. The file is only expanded if the source
file is newer than the destination file, or when the destination file
does not exist.</p>
