# change to match your directories
#     it is suggested that you place things like libpng and zlib in 
#     version-specific directories like ../zlib-1.0 and that you make a 
#     symbolic link like "ln -s zlib-1.0 zlib" in the .. directory 

# where "make install" puts pnmtopng and pngtopnm
#INSTDIR=/Users/Willem/Unix
