| 35 | =head1 NAME |
| 36 | |
| 37 | Pod::Plainer - Perl extension for converting Pod to old style Pod. |
| 38 | |
| 39 | =head1 SYNOPSIS |
| 40 | |
| 41 | use Pod::Plainer; |
| 42 | |
| 43 | my $parser = Pod::Plainer -> new (); |
| 44 | $parser -> parse_from_filehandle(\*STDIN); |
| 45 | |
| 46 | =head1 DESCRIPTION |
| 47 | |
| 48 | Pod::Plainer uses Pod::Parser which takes Pod with the (new) |
| 49 | 'CE<lt>E<lt> .. E<gt>E<gt>' constructs |
| 50 | and returns the old(er) style with just 'CE<lt>E<gt>'; |
| 51 | '<' and '>' are replaced by 'EE<lt>ltE<gt>' and 'EE<lt>gtE<gt>'. |
| 52 | |
| 53 | This can be used to pre-process Pod before using tools which do not |
| 54 | recognise the new style Pods. |
| 55 | |
| 56 | =head2 EXPORT |
| 57 | |
| 58 | None by default. |
