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

SYNOPSIS
           use CGI::Pretty qw( :html3 );

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

DESCRIPTION
       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:
           
foo

       If a user were to create a table consisting of many rows and many col-
       umns, 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:
           

              

                 

                    foo

       The  and 
 tags are not formatted.  If these tags were format-
       ted, the user would see the extra indentation on the web browser caus-
       ing 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 @ASIS array:

           push @CGI::Pretty::ASIS,qw(CODE XMP);

       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 = "";
