CGI::Pretty Adds carriage returns and intentation to HTML generated by CGI.pm % perl -e 'use CGI qw{:standard}; print table( TR( td( "foo" ) ) );' <table><tr><td>foo</td></tr></table> Ugh. % perl -e 'use CGI::Pretty qw{:standard}; print table( TR( td( "foo" ) ) );' <table> <tr> <td> foo </td> </tr> </table> Better! Not perfect indentation always; Not useful if you don't generate HTML with CGI.pm.
