 <li>MESA_GLSL_VERSION_OVERRIDE - changes the value returned by
 glGetString(GL_SHADING_LANGUAGE_VERSION). Valid values are integers, such as
 "130".  Mesa will not really implement all the features of the given language version
 if it's higher than what's normally reported. (for developers only)
 <li>MESA_GLSL_CACHE_DISABLE - if set, disables the GLSL shader cache
 <li>MESA_GLSL_CACHE_MAX_SIZE - if set, determines the maximum size of
 the on-disk cache of compiled GLSL programs. Should be set to a number
 optionally followed by 'K', 'M', or 'G' to specify a size in
 kilobytes, megabytes, or gigabytes. By default, gigabytes will be

+cache might be created for each architecture that Mesa is installed for on
+your system. For example under the default settings you may end up with a 1GB
+cache for x86_64 and another 1GB cache for i386.
 <li>MESA_GLSL_CACHE_DIR - if set, determines the directory to be used
 for the on-disk cache of compiled GLSL programs. If this variable is
 not set, then the cache will be stored in $XDG_CACHE_HOME/mesa (if
 that variable is set), or else within .cache/mesa within the user's
 home directory.
