949 it won't do any good to turn the checking flags on; if a checking flag
950 is off, it doesn't do any good to ask for generation of warnings or errors.
951 Also libmng will generate either an error or a warning, not both,
952 so if you specify both the default will be to generate an error!

954 and optionally 031 and 051, but only checking ancillary chunks and not
955 critical chunks is generally not a very good idea!!!

967
968 If you have defined MNG_FULL_CMS (and are using lcms), you will have to
969 think hard about the following routines.
970
971 lcms requires 2 profiles to work off the differences in the input-image
972 and the output-device. The ICC profile for the input-image will be
973 embedded within it to reflect its color-characteristics, but the output
974 profile depends on the output-device, which is something only *YOU* know
975 about. sRGB (standard RGB) is common for x86 compatible environments
976 (eg. Windows, Linux and some others)
977
978 If you are compiling for a sRGB compliant system you probably won't have
979 to do anything special. (unless you want to of course)
980
981 If you are compiling for a non-sRGB compliant system
982 (eg. SGI, Mac, Next, others...)
983 you *MUST* define a proper ICC profile for the generic output-device
984 associated with that platform.
985
986 In either event, you may also want to offer an option to your users to
987 set the profile manually, or, if you know how, set it from a
988 system-defined default.
989
990 TO RECAP: for sRGB systems (Windows, Linux) no action required!
991 for non-sRGB systems (SGI, Mac, Next) ACTION REQUIRED!
