The different kinds of vaults used by Crawl are described briefly below. In
most cases, when the dungeon builder places a vault on a level, the rest of
the level (assuming the vault is not a full-map vault) is generated as
rooms+corridors. The only exceptions to this are branch entry vaults and
minivaults - these are placed after the level is generated, and therefore
do not influence level generation.
