# Long definition during trace processing

# in this example, if input traces contain headers 'ffid', 'espnum', 'sou_lin' and 'sou_stn',
# then for every trace passing this tool, the 'define' call will set  a text substitution 'title'
# containing the values of these headers. This title can be used, for example, to form
# plot headers.
