#-----------------------------------------------------------------------------
#   GNU makefile for WCSLIB 4.3 utilities: fitshdr, HPXcvt and wcsgrid.
#
#   Summary of the main targets
#   ---------------------------
#      build:     Build all utilities.
#      clean (or cleaner): Delete intermediate object files.
#      realclean (or cleanest): cleaner, and also delete the executables.
#
#   Notes:
#      1) If you need to make changes then preferably modify ../makedefs.in
#         instead and re-run configure.
#
#      2) In compiling these utilities, this makefile assumes that the
#         WCSLIB 4.3 sources reside in ../{pgsbox,C} (as in the distribution
#         kit).
