Following that is a series of event lines. Each event begins with an
event name, followed by zero or more named unsigned integer arguments.
Names are separated from their integer values by an '=' sign. Names can
consist of any UTF-8 character except '='.

For example:

	EventName arg1=23 arg2=55 arg3=53

Any amount of whitespace is allowed to separate each token. Whitespace
is identified via unicode.IsSpace.
