package main
// This program takes a .zim-file and dumps all contained articles below the
// current directory. I tested it with a Wikipedia snapshot; that did not
// contain deleted articles or LinkTargetEntrys, so I'm unsure how to handle
// those, for now I'm ignoring them.
//
// Redirects are handled by simply writing out the page pointed to by the
// redirect. IPFS deduplication should take care of it, so I think this is the
// most economical solution, even better than writing out small HTML files with
