Well, no, not really.  The ice-9 printf is (with minor schemification
like using #f instead of nil) just an implementation of Common Lisp
format (I forgot to say that explicitly).  The specs for CL format
take more than 25 pages in Guy Steele's terse style.

In general, a format spec is a tilde, parameters separated by
commas, optional colon, optional at sign, and the format directive
character.  The info files in Guile enumerate the directives,
but are missing descriptions of what the arguments do.  Somebody
should fill that in, but I am not going to type it into this mail
message.  In general the first parameter is often (not always)
the minimum width.  Character parameters are preceded by a single
quote.
