|
|
|
This is probably the most important role in the Pod-Elemental distribution. |
91
|
|
|
|
|
|
|
Classes including this role represent paragraphs in a Pod document. The |
92
|
|
|
|
|
|
|
paragraph is the fundamental unit of dividing up Pod documents, so this is a |
93
|
|
|
|
|
|
|
often-included role. |

=head1 PERL VERSION |
96
|
|
|
|
|
|
|
|
97
|
|
|
|
|
|
|
This library should run on perls released even a long time ago. It should work |
98
|
|
|
|
|
|
|
on any version of perl released in the last five years. |
99
|
|
|
|
|
|
|
|
100
|
|
|
|
|
|
|
Although it may work on older versions of perl, no guarantee is made that the |
101
|
|
|
|
|
|
|
minimum required version will not be increased. The version may be increased |
102
|
|
|
|
|
|
|
for any reason, and there is no promise that patches will be accepted to lower |
103
|
|
|
|
|
|
|
the minimum required perl. |

This returns the element as a string, suitable for turning elements back into |
126

a document. Some elements, like a C<=over> command, will stringify to include |
