      5 #	The programs built by this makefile are described in the book,
      6 #	"PNG:  The Definitive Guide," by Greg Roelofs (O'Reilly and
      7 #	Associates, 1999).  Go buy a copy, eh?  Buy some for friends
      8 #	and family, too.  (Not that this is a blatant plug or anything.)
      9 #
     10 # Invoke this makefile from a shell prompt in the usual way; for example:
     11 #
     12 #	make -f Makefile.sgi
     13 #
     14 # This makefile assumes libpng and zlib have already been built or downloaded
     15 # and are both installed in /usr/local/{include,lib} (as indicated by the
     16 # PNG* and Z* macros below).  Edit as appropriate--choose only ONE each of
     17 # the PNGINC, PNGLIB, ZINC and ZLIB lines.
     18 #
     19 # This makefile builds dynamically linked executables (against libpng and zlib,
     20 # that is), but that can be changed by uncommenting the appropriate PNGLIB and
     21 # ZLIB lines.
