Print information on GD library's version, configuration, and use.
Usage: gdlib-config [options]
Options:
	--libdir          # directory where GD library is installed
	--includedir      # directory where GD library headers are installed
	--version         # complete GD library version string
	--majorversion    # GD library major version number
	--minorversion    # GD library minor version number
	--revision        # GD library revision version number
	--ldflags         # options required for linking against GD library
	--libs            # libs required for linking against GD library
	--cflags          # options required for compiling GD library apps
	--includes        # same as --cflags
	--features        # lists optional features compiled into gd, separated
                          # by spaces. Currently (as of 2.0.26) the optional
                          # features are GD_PNG, GD_JPEG, GD_XPM, and
                          # GD_FREETYPE. When these features are reported by
                          # --features, it is safe to include calls to the
                          # related functions in your code.
	--all             # print a summary of all GD library configure options
