# section-parse.rb: scan standard input and do the following:
#
# 1. look for a section that begins with "test-text "STUFF/foo" and ends
#    with a blank line.
# 2. print the "bar.DIGITS" suffix for each line in the section
#
# Example:
#   > cat input.txt
#   test-text "blah blah blah garbage/foo"
#   random crap bar.1
#   random crap bar.2
#   random crap bar.3
#   random crap bar.4
#   
#   test-text "blah blah blah garbage/apple"
#   random crap bar.1
#   random crap bar.2
#   random crap bar.3
#   random crap bar.4
#   > ./section-parse.rb < input.txt
#   bar.1
#   bar.2
#   bar.3
#   bar.4

  # 1. we are outside the section and the current line is the matching
  #    section header
  # 2. we are in the section body and the current line is empty
  if (!in_body && s =~ /^test-text ".*\/foo"$/) || (in_body && s =~ /^\s*$/)
