Tagmerger

A small tool to help merging a messy set of tags into a new, hopefully cleaner set.

Very much work in progress, and best effort.

Tags are exported in a yaml file. Each key corresponds to a tag in the messy set, and contains a list of tags of the new set to which this tag should be merged.

The script can take the yaml file back as input, which allows pausing and restarting the tag merging process.
