# File lib/ceedling/makefile.rb, line 27
def process_line(line)
  # split on presence of task demaractor followed by space (i.e don't get confused by a colon in a win path)
  file_tasks, args = line.split(/:\s/)

  return if args.nil?
  
  # split at non-escaped space boundary between files (i.e. escaped spaces in paths are left alone)
  dependents = args.split(/\b\s+/)
  # replace escaped spaces and clean up any extra whitespace
  dependents.map! { |path| path.gsub(/\\ /, ' ').strip }

  file_tasks.strip.split.each do |file_task|
    file file_task => dependents
