+  If the background process does not output to the compilation buffer,
+so you only need to prevent it from being killed when the main
+compilation process terminates, this is sufficient:
+
+@example
+nohup @var{command}; sleep 1
+@end example
+
+@vindex compilation-environment
+  You can control the environment passed to the compilation command
+with the variable @code{compilation-environment}.  Its value is a list
+of environment variable settings; each element should be a string of
+the form @code{"@var{envvarname}=@var{value}"}.  These environment
+variable settings override the usual ones.
