# Exception extension that tweaks Exception backtraces:
#
# * The line of the failing .feature line is appended to the backtrace
# * The line that calls #cucumber_instance_exec is replaced with the StepDefinition's regexp
# * Non intersting lines are stripped out
#
# The result is that backtraces look like this:
#
# features/step_definitions/the_step_definition.rb:in `/some step/'
# features/the_feature_file.feature:41:in `Given some step'
#
# or if the exception is raised in the tested code:
#
# lib/myapp/some_file.rb:in `/some_method/'
# lib/myapp/some_other_file.rb:in `/some_other_method/'
# features/step_definitions/the_step_definition.rb:in `/some step/'
# features/the_feature_file.feature:41:in `Given some step'
#
# All backtrace munging can be turned off with the <tt>--backtrace</tt> switch
#
