# Tests for indent that focus on comparing the effects of the various command
# line options.
#
# The test files contain the input to be formatted, the formatting options
# and the output, all as close together as possible. The test files use the
# following directives:
#
#	//indent input [description]
#		Specifies the input to be formatted.
#	//indent run [options]
#		Runs indent on the input, using the given options.
#	//indent end [description]
#		Finishes an '//indent input' or '//indent run' section.
#	//indent run-equals-input [options]
#		Runs indent on the input, expecting unmodified output.
#	//indent run-equals-prev-output [options]
#		Runs indent on the input, expecting the same output as from
#		the previous run.
#
# All text outside these directives is not passed to indent.
