+@code{setenv} adds @var{name} to the environment with value
+@var{value}. If the name was already present in the environment,
+the new value will be stored only if @var{overwrite} is non-zero.
+The companion @code{unsetenv} function removes @var{name} from the
+environment. This implementation is not safe for multithreaded code.
