     31 # line options.

     33 # The test files contain the input to be formatted, the formatting options
     34 # and the output, all as close together as possible. The test files use the
     35 # following directives:
     36 #
     37 #	#indent input [description]
     38 #		Specifies the input to be formatted.
     39 #	#indent run [options]
     40 #		Runs indent on the input, using the given options.
     41 #	#indent end [description]
     42 #		Finishes an 'input' or 'run' section.
     43 #
     44 # All text between these directives is not passed to indent.
