This program is useful in determining differences between
two files or directories. It produces a list of
lines that must be changed (c), appended (a), or deleted (d) to make
the first file match the second. Lines from the first file are prefixed
by "<" and lines from the second are prefixed by ">".
The -b option ignores trailing blanks and treats all other
strings of blanks as equivalent.
The -i option removes case sensitivity so that uppercase and
lowercase letters match.
