+
+;;; Commentary:
+
+;; Usage: summarize-guile-TODO TODOFILE
+;;
+;; The TODOFILE is typically Guile's (see workbook/tasks/README)
+;; presumed to serve as our signal to ourselves (lest we want real
+;; bosses hassling us) wrt to the overt message "items to do" as well as
+;; the messages that can be inferred from its structure.
+;;
+;; This program reads TODOFILE and displays interpretations on its
+;; structure, including registered markers and ownership, in various
+;; ways.
+;;
+;; A primary interest in any task is its parent task. The output
+;; summarization by default lists every item and its parent chain.
+;; Top-level parents are not items. You can use these command-line
+;; options to modify the selection and display (selection criteria
+;; are ANDed together):
+;;
+;; -i, --involved USER -- select USER-involved items
+;; -p, --personal USER -- select USER-responsible items
+;; -t, --todo -- select unfinished items (status "-")
+;; -d, --done -- select finished items (status "+")
+;; -r, --review -- select review items (marker "R")
+;;
+;; -w, --who -- also show who is associated w/ the item
+;; -n, --no-parent -- do not show parent chain
+;;
+;;
+;; Usage from a Scheme program:
+;; (summarize-guile-TODO . args) ; uses first arg only
+;;
+;;
+;; Bugs: (1) Markers are scanned in sequence: D R X N%. This means "XD"
+;; and the like are completely dropped. However, such strings
+;; are unlikely to be used if the markers are chosen to be
+;; somewhat exclusive, which is currently the case for D R X.
+;; N% used w/ these needs to be something like: "D25%" (this
+;; means discussion accounts for 1/4 of the task).
+;;
+;; TODO: Implement more various ways. (Patches welcome.)
+;; Add support for ORing criteria.
