Description: |
From time to time, a janitor has to clean up a thread where the original poster chose a bad title for his question. If the janitor is too late, there are many nodes to retitle. This WWW::Mechanize script automates this process.
Of course, this script will only work, if you are a janitor, and it will break horribly if the PerlMonks HTML changes enough.
Update: castaway noted that the retitler broke due to recent changes in how internal links are done. The current version fixes that. |
