#-----------------------------------------------------------------------------
# GNU makefile for building WCSLIB 6.2
#
# Summary of the main targets
# ---------------------------
#   all:       Do 'make all' in each subdirectory (excluding ./doxygen).
#   check:     Do 'make check' in each subdirectory (compile and run tests).
#   tests:     Do 'make tests' in each subdirectory (compile test programs but
#              don't run them).
#   install:   Do 'make install' in each subdirectory.
#   clean:     Recursively delete intermediate files produced as part of the
#              build, e.g. object modules, core dumps, etc.
#   cleaner:   Recursively clean, and also delete test executables, test
#              input and output, and intermediates produced in compiling the
#              programmers' manual.
#   distclean (or realclean): Recursively delete all platform-dependent files
#              generated during the build, preserving only the programmers'
#              manual and man pages (which are normally provided pre-built).
#              It is the one to use between builds for multiple platforms.
#   cleanest:  Like distclean, but deletes everything that can be regenerated
#              from the source files, including the programmers' manual and
#              man pages, but excluding 'configure'.
#   show:      Print the values of important variables used in this and the
#              other makefiles.
#   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 makefiles in subdirectories, particularly
#      C/GNUmakefile.
