  18 ## Because some of our examples use
  19 ##
  20 ##     %C%_reccalc_SOURCES = %D%/parse.y
  21 ##
  22 ## Automake ships parse.y and parse.c, and possibly parse.h when it
  23 ## "understands" that there is one.  This is not what we want: ship only
  24 ## parser.y.  Yet we still want to use Automake to compile the sources
  25 ## from parser.y.  The easiest seems to use
  26 ##
  27 ##     nodist_%C%_reccalc_SOURCES = %D%/parse.y
  28 ##
  29 ## together with
  30 ##
  31 ##     dist_reccalc_DATA = %D%/parse.y %D%/scan.l %D%/Makefile %D%/README.md
  32 ##
  33 ## which guarantees that parse.y is indeed shipped.
