-       Usage: tg export ([--collapse] BRANCH | --quilt DIR)
+       In '--quilt' mode the patches are named like the originating topgit
+       branch.  So usually they end up in subdirectories of the output
+       directory.  With option '--flatten' the names are mangled such that
+       they end up directly in the output dir (i.e. slashed are substituted by
+       underscores).  With '--numbered' (which implies '--flatten') the patch
+       names get a number as prefix to allow getting the order without
+       consulting the series file, which eases sending out the patches.
