<p>TextFile instances can be used like normal file objects
(i.e. by calling readline(), readlines(), and write()), but can
also be used as sequences of lines in for-loops.</p>
<p>TextFile objects also handle compression transparently. i.e. it is
possible to read lines from a compressed text file as if it were not
compressed. Compression is deduced from the file name suffixes <tt>.Z</tt>
(compress/uncompress), <tt>.gz</tt> (gzip/gunzip), and <tt>.bz2</tt> (bzip2).</p>
<p>Finally, TextFile objects accept file names that start with <tt>~</tt> or
<tt>~user</tt> to indicate a home directory, as well as URLs (for reading only).</p>
<p>Constructor: TextFile(<i>filename</i>, <i>mode</i>=<tt>"r"</tt>), where <i>filename</i> is
the name of the file (or a URL) and <i>mode</i> is one of <tt>"r"</tt> (read),
<tt>"w"</tt> (write) or <tt>"a"</tt> (append, not supported for .Z files).
