;;; Commentary:

;; Usage: todo [OPTIONS] [PROJECT]
;;
;; Summarize PROJECT's todo file using "guile-tools summarize-guile-TODO".
;; PROJECT is a regular expression that may match one or more todo file
;; names registered in the meta data file (see `--meta' below).  If PROJECT
;; is omitted, all projects are selected.
;;
;; OPTIONS are zero or more of:
;;  -L, --list       -- display mtime and name of each todo file regsitered
;;  -M, --meta FILE  -- use FILE for meta data [default: $HOME/.todo.list]
;;
;; These options are also accepted (passed through to summarize-guile-TODO):
;;  -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
