Refactor or convert markdown-based static sites.
This has been written to evaluate and perform the transition from my ikiwiki-based site to another site generator, and has evolved instead as a tool to clean up, refactor, check and maintain my ikiwiki site.
It is able to parse the subset of ikiwiki's markdown that I use into a logical representation, and from there it is easy to move pages fixing their links, or generate output for other engines like hugo, pelican or nikola.
