+
+ If you have defined MNG_FULL_CMS (and are using lcms), you will have to
+ think hard about the following routines.
+
+ lcms requires 2 profiles to work off the differences in the input-image
+ and the output-device. The ICC profile for the input-image will be
+ embedded within it to reflect its color-characteristics, but the output
+ profile depends on the output-device, which is something only *YOU* know
+ about. sRGB (standard RGB) is common for x86 compatible environments
+ (eg. Windows, Linux and some others)
+
+ If you are compiling for a sRGB compliant system you probably won't have
+ to do anything special. (unless you want to of course)
+
+ If you are compiling for a non-sRGB compliant system
+ (eg. SGI, Mac, Next, others...)
+ you *MUST* define a proper ICC profile for the generic output-device
+ associated with that platform.
+
+ In either event, you may also want to offer an option to your users to
+ set the profile manually, or, if you know how, set it from a
+ system-defined default.
+
+ TO RECAP: for sRGB systems (Windows, Linux) no action required!
+ for non-sRGB systems (SGI, Mac, Next) ACTION REQUIRED!
+
+ Please visit http://www.srgb.com, http://www.color.org and
