			:: Allows multiple filter instances to use differently named conditional parameters, thus preventing collision and overwrite of variables which are used by different ConditionalReader instances.
			:: See Conditional Variables section of http://avisynth.nl/index.php/ColorYUV.
			:: How does it work: when reading the global variables, the "condvarsuffix" parameter is appended to the variable name.
			:: E.g. ColorYUV will read "coloryuv_gain_y_a" instead of "coloryuv_gain_y" when condvarsuffix = "_a" is provided for ColorYUV.
			:: In the matching ConditionalReader one have to use the modified name as well:

			<div {{BoxWidthIndent\|80\|2}} >
			ConditionalReader("coloryuvoffset.txt", "coloryuv_gain_y", false, CondVarSuffix = "_a") # "_a" is added here by parameter
			ConditionalReader("rgbfix.txt", "rgbadjust_r", false, CondVarSuffix = "_1") # "_1" is added here by parameter
			ConditionalReader("rgbfix2.txt", "rgbadjust_r", false, CondVarSuffix = "_2") # "_2" is added here by parameter
			</div>

			:: or specify the suffixed name directly:

			<div {{BoxWidthIndent\|76\|2}} >
			ConditionalReader("coloryuvoffset.txt", "coloryuv_gain_y_a", false) # "_a" is added here manually
			</div>
