+# automatic case
+# git-debrebase new-upstream
+# - previous breakwater merge must be gdr-generated
+# - orig set is the same as before
+# - implicitly uses upstream branches according to orig set
+# - not all upstream branches need be updated
+# - insists on fast-forward of each branch, unless
+# --force (or --force=<subdir>[/])
+# branch set adjustments
+# git-debrebase new-upstream --add <subdir>/
+# git-debrebase new-upstream --rm <subdir>/
+# git-debrebase new-upstream / [<subdir>/ ...]
+# - orig set is adjusted
+# - otherwise like auto (--add is not checked for ffness, obv)
+# - multiple --add and --rm may be specified
+# - --add makes new upstream the last contributor
+# explicit
+# git-debrebase / [<rootcommitid>] [<subdir>/ [<commitid>] ...]
+# - orig set is precisely as specified now
+# - previous breakwater merge is irrelevant
+# - no fast forward checks
+# for now only explicit with commitids
+
+ # implicitly uses `upstream'
+# # (or multiple other branches)
+# git-debrebase new-upstream \
+# [<subdir>/]=<commitid>
