+;;; Commentary:
+
+;; * This module exports:
+;;
+;; file-commentary -- a procedure that returns a file's "commentary"
+;;
+;; documentation-files -- a search-list of files using the Guile
+;; Documentation Format Version 2.
+;;
+;; search-documentation-files -- a procedure that takes NAME (a symbol)
+;; and searches `documentation-files' for
+;; associated documentation. optional
+;; arg FILES is a list of filenames to use
+;; instead of `documentation-files'.
+;;
+;; object-documentation -- a procedure that returns its arg's docstring
+;;
+;; * Guile Documentation Format
+;;
+;; Here is the complete and authoritative documentation for the Guile
+;; Documentation Format Version 2:
+;;
+;; HEADER
+;; ^LPROC1
+;; DOCUMENTATION1
+;;
+;; ^LPROC2
+;; DOCUMENTATION2
+;;
+;; ^L...
+;;
+;; The HEADER is completely ignored. The "^L" are formfeeds. PROC1, PROC2
+;; and so on are symbols that name the element documented. DOCUMENTATION1,
+;; DOCUMENTATION2 and so on are the related documentation, w/o any further
+;; formatting. Note that there are two newlines before the next formfeed;
+;; these are discarded when the documentation is read in.
+;;
+;; (Version 1, corresponding to guile-1.4 and prior, is documented as being
+;; not documented anywhere except by this embarrassingly circular comment.)
+;;
+;; * File Commentary
+;;
+;; A file's commentary is the body of text found between comments
+;; ;;; Commentary:
+;; and
+;; ;;; Code:
+;; both of which must be at the beginning of the line. In the result string,
+;; semicolons at the beginning of each line are discarded.
+;;
+;; You can specify to `file-commentary' alternate begin and end strings, and
+;; scrub procedure. Use #t to get default values. For example:
+;;
+;; (file-commentary "documentation.scm")
+;; You should see this text!
+;;
+;; (file-commentary "documentation.scm" "^;;; Code:" "ends here$")
+;; You should see the rest of this file.
+;;
+;; (file-commentary "documentation.scm" #t #t string-upcase)
+;; You should see this text very loudly (note semicolons untouched).
+
+;;; Code:
