A script that tries to automate the process of upgrading the wiki.
Download from github (Click "Downloads" in the tab menu). Install in /usr/local/bin
Edit the script to set WIKI_ROOT to the place where your wiki is installed, up to and including the "wiki/" path component. Set the other *_ROOT variables as needed and create any needed dirs.
run as root: upgrade-pmwiki.sh
Feel free to download the script from github, make it better (see TODO list in the file) then release to the community. Please keep my original author attribution in the file.
