## Use:
These configuration values can be changed at runtime by including this in your
program:
<!--?prettify?-->
~~~~
#include "SkRTConf.h"
/*...*/
int main() {
SK_CONF_SET( configuration_name, new_value );
/*...*/
~~~~
Or by setting the corresponding environment variable before starting the
program. For example, in Bourne shell:
<!--?prettify?-->
~~~~
#!/bin/sh
export skia_environment_variable="new_value"
your_program
~~~~
