MoinMoin - data_dir migration main script (new style)
You can use this script to migrate your wiki's data_dir to the format
expected by the current MoinMoin code. It will read data/meta to determine
what needs to be done and call other migration scripts as needed.
You must run this script as owner of the wiki files, usually this is the
web server user (like www-data).
Important: you must have run all 12_to_13* and the final 152_to_1050300
mig scripts ONCE and in correct order manually before attempting
to use the new style migration stuff.
