       CGI::Pretty - module to produce nicely formatted HTML code

	   use CGI::Pretty qw( :html3 );

	   # Print a table with a single data element
	   print table( TR( td( "foo" ) ) );

       CGI::Pretty is a module that derives from CGI.  It's sole function is
       to allow users of CGI to output nicely formatted HTML code.

       When using the CGI module, the following code:
	   print table( TR( td( "foo" ) ) );

       produces the following output:

       If a user were to create a table consisting of many rows and many
       columns, the resultant HTML code would be quite difficult to read since
       it has no carriage returns or indentation.

       CGI::Pretty fixes this problem.	What it does is add a carriage return
       and indentation to the HTML code so that one can easily read it.

	   print table( TR( td( "foo" ) ) );

       now produces the following output:

   Recommendation for when to use CGI::Pretty
       CGI::Pretty is far slower than using directly. A benchmark
       showed that it could be about 10 times slower. Adding newlines and
       spaces may alter the rendered appearance of HTML. Also, the extra
       newlines and spaces also make the file size larger, making the files
       take longer to download.

       With all those considerations, it is recommended that CGI::Pretty be
       used primarily for debugging.

   Tags that won't be formatted
       The following tags are not formatted: <a>, <pre>, <code>, <script>,
       <textarea>, and <td>.  If these tags were formatted, the user would see
       the extra indentation on the web browser causing the page to look
       different than what would be expected.  If you wish to add more tags to
       the list of tags that are not to be touched, push them onto the @AS_IS

	   push @CGI::Pretty::AS_IS,qw(XMP);

   Customizing the Indenting
       If you wish to have your own personal style of indenting, you can
       change the $INDENT variable:

	   $CGI::Pretty::INDENT = "\t\t";

       would cause the indents to be two tabs.

       Similarly, if you wish to have more space between lines, you may change
       the $LINEBREAK variable:

	   $CGI::Pretty::LINEBREAK = "\n\n";

       would create two carriage returns between lines.

       If you decide you want to use the regular CGI indenting, you can easily
       do the following:

	   $CGI::Pretty::INDENT = $CGI::Pretty::LINEBREAK = "";
