#-----------------------------------------------------------------------------
#   GNU makefile for building WCSLIB 4.3.
#
#   Summary of the main targets
#   ---------------------------
#      all:       Do 'make all' in each subdirectory.
#      check:     Do 'make check' in each subdirectory.
#      tests:     Do 'make tests' in each subdirectory.
#      install:   Do 'make install' in each subdirectory.
#      realclean (or cleanest): Do 'make realclean' in each subdirectory.
#      show_all:  Print the values of all variables used in this GNUmakefile.
#      writable:  Run chmod recursively to make all sources writable.
#
#   Notes:
#      1) If you need to make changes then preferably modify makedefs.in
#         instead.
#
#      2) Refer also to the GNUmakefiles in subdirectories, particularly
#         C/GNUmakefile.
