+Programming interfaces are now summarized in doc/guile-api.alist, in a
+program-friendly format.  This file contains a single sexp of the form:
 
-  ((scheme SCHEME-API) (C C-API))
+  ((meta ...) (interface ...))
 
-SCHEME-API and C-API are sub-alists whose keys are names of Scheme (or
-C) functions and variables.  The values behind the keys are unspecified
-for now.
+The meta fields are `GUILE_LOAD_PATH', `LTDL_LIBRARY_PATH', `guile'
+`libguileinterface', `sofile' and `groups'.  The interface elements are
+in turn sub-alists w/ keys `groups' and `scan-data'.  Interface elements
+initially belong in one of two groups `Scheme' or `C' (but not both) and
+sometimes belong in other groups (see doc/groupings.alist for defs).
