[[!tag plugins/meta patch]]

I'd like to define [[plugins/meta]] values to apply across all pages
|
|
site-wide unless the pages define their own: default values for meta
|
|
definitions essentially.
|
|
|
|
Here's a patch to achieve this (also in the "defaultmeta" branch of
|
|
my github ikiwiki fork):

The field values are treated as HTML entity-escaped text, so you can include

a quote in the text by writing `"` and so on.
