This plugin allows the administrator of a wiki to lock some pages, limiting who can edit them using the online interface. This doesn't prevent anyone who can commit to the underlying revision control system from editing the pages, however. (Unless you set up untrusted git push.)
locked_pages setting configures what pages are locked. It is a
PageSpec, so you have lots of control over what kind of pages
to lock. For example, you could choose to lock all pages created before
2006, or all pages that are linked to from the page named "locked". More
usually though, you'll just list some names of pages to lock.
Wiki administrators can always edit locked pages. The PageSpec
can specify that some pages are not locked for some users. For example,
"important_page and !user(joey)" locks
important_page while still
allowing joey to edit it, while "!*/Discussion and user(bob)" prevents bob
from editing pages except for Discussion pages.
