# Generic rules to create an haskell data type module and its pretty-printer
# from a SDF grammar file.
#
# This makefile requires three global variables:
#   SDF2HASKELL    - Program configuration of "Sdf2Haskell"
#                    (in makerules.configuration)
#   SDFGRAMMAR     - file name with full path of the sdf grammar file
#                    (defined in the makefile that imports this)
#   HASKELL_MODULE - name to be used in the module hierarchy (eg. Data.XYZ.)
#                    (defined in the makefile that imports this)
