`info.ss` File Format

An info.ss file provides general information about a collection. The file must have the following format:

(module info (lib "infotab.ss" "setup")
   (define identifier info-expr)
   ···)

info-expr is one of
  (quote datum)
  (quasiquote datum) ; with unquote and unquote-splicing
  (info-primitive info-expr ···)
  identifier ; an identifier defined in the info module
  literal ; a string, number, boolean, etc.

info-primitive is one of
  cons car cdr list
  list* reverse append
  build-path collection-path
  system-library-subpath

For example, the following declaration is in the info.ss library of the help collection. It contains definitions for three info tags:

(module info (lib "infotab.ss" "setup")
  (define name "Help")
  (define mred-launcher-libraries (list "help.ss"))
  (define mred-launcher-names (list "Help Desk")))

The setup collection's getinfo.ss library defines a get-info function for extracting field values from a collection's info.ss file. See the setup collection's documentation for details.
