% Underlining in gb4e-example Environments. Usual underlining commands that span multiple words do not work, because gb4e would parse it as one word.

% Note: The 2nd Argument of the \ulp command is filled in by experience - if you are not familiar with the command, you should experiment a bit. Usually, five tildes are enough, but be sure to check the outcome.
