Function Details

lines_of_file(filename)

Return a list containing the lines of a file, with newlines
stripped.

read_boolean(b)

Read a boolean from whatever we offer as boolean value, and
return real boolean values 0 and 1, or raise an exception.

write_lines_to_file(filename, lines)

Write lines to filename, appending newlines to each.

write_lines_to_file_if_changed(filename, lines)

Write lines to filename if the lines are not what the file
has, or if the file does not exist. (It's not that writing the
file should be considered expensive; rather, writing the file
unnecessarily can be expensive if the file is a dependency of
another file in the build process.)
