* Makefile to:
  * Build or download remote OPMLs:
    * From mailing list archives
    * From gitweb, like https://git.sarava.org/?a=opml
  * Compile an `all.opml` which includes all other OPMLs in the repository.
* Cleanup and split `feeds.opml` into distinct OPML files. Use hierarchy to keep tagging.
