 #    dmake supports an alternative form for its recipes, called "group
-#    recipes", in which all elements of a recipe are run with only one
-#    shell.  This program converts the standard dmake makefile.mk to
-#    one using group recipes. This is done so that lines using && or
-#    || (which command.com doesn't understand) may be split into two
-#    lines.
