16

|

|
|
|
|
17
|
|
|
|
|
|
|
This will cause problems with Pod::Abstract documents frozen to disk |
18
|
|
|
|
|
|
|
using Data::Dumper etc, unless C is used to bump the number above |
19
|
|
|
|
|
|
|
the highest number read. |
20
|
|
|
|
|
|
|
|
21
|
|
|
|
|

|
Or just serialise your document with C<< $node->pod >> instead! |
