When I decided to drop Wiki Wirds, uninstall the Local Names Extension and uninstall the Usemod Markup Extension from my homepage, I had a lot of markup that would no longer work. These are the files I used to migrate my data directory.

Usage: $0 [--dir=DIR]
|
|
|
|
You need to use the raw.pl script to create a directory full of raw
|
|
wiki text files.
|
|
|
|
--dir=DIR is where the raw wiki text files are. Default: raw. The
|
|
converted files will be stored in DIR-new, ie. in raw-new by
|
|
default.
|
|
|
|
Example: $0 --dir=~/alexschroeder/raw
|
|

|
