## Because some of our examples use
##
##     %C%_reccalc_SOURCES = %D%/parse.y
##
## Automake ships parse.y and parse.c, and possibly parse.h when it
## "understands" that there is one.  This is not what we want: ship only
## parser.y.  Yet we still want to use Automake to compile the sources
## from parser.y.  The easiest seems to use
##
##     nodist_%C%_reccalc_SOURCES = %D%/parse.y
##
## together with
##
##     dist_reccalc_DATA = %D%/parse.y %D%/scan.l %D%/Makefile %D%/README.md
##
## which guarantees that parse.y is indeed shipped.
