Note, however, that (a) some stuff simply doesn't belong into man pages (e.g., details of troff internals – the perl way of having zillions of man pages is not very attractive to me), and that (b) info files can be far more explicit, accompanied with examples, say. So both have a sensible purpose, but there is a very large, unavoidable overlap in information. Werner
