+# Module ndiff version 1.7.0
+# Released to the public domain 08-Dec-2000,
+# by Tim Peters (tim.one@home.com).
+
+# Provided as-is; use at your own risk; no warranty; no promises; enjoy!
+
+# ndiff.py is now simply a front-end to the difflib.ndiff() function.
+# Originally, it contained the difflib.SequenceMatcher class as well.
+# This completes the raiding of reusable code from this formerly
+# self-contained script.
+
+"""ndiff [-q] file1 file2
+    or
+ndiff (-r1 | -r2) < ndiff_output > file1_or_file2
+
+Print a human-friendly file difference report to stdout.  Both inter-
+and intra-line differences are noted.  In the second form, recreate file1
+(-r1) or file2 (-r2) on stdout, from an ndiff report on stdin.
+
+In the first form, if -q ("quiet") is not specified, the first two lines
+of output are
+
+-: file1
++: file2
+
+Each remaining line begins with a two-letter code:
+
+    "- "    line unique to file1
+    "+ "    line unique to file2
+    "  "    line common to both files
+    "? "    line not present in either input file
+
+Lines beginning with "? " attempt to guide the eye to intraline
+differences, and were not present in either input file.  These lines can be
+confusing if the source files contain tab characters.
+
+The first file can be recovered by retaining only lines that begin with
+"  " or "- ", and deleting those 2-character prefixes; use ndiff with -r1.
+
+The second file can be recovered similarly, but by retaining only "  " and
+"+ " lines; use ndiff with -r2; or, on Unix, the second file can be
+recovered by piping the output through
+
+    sed -n '/^[+ ] /s/^..//p'
