+Using diff-highlight as a module
+--------------------------------
+
+If you want to pre- or post- process the highlighted lines as part of
+another perl script, you can use the DiffHighlight module. You can
+either "require" it or just cat the module together with your script (to
+avoid run-time dependencies).
+
+Your script may set up one or more of the following variables:
+
+  - $DiffHighlight::line_cb - this should point to a function which is
+    called whenever DiffHighlight has lines (which may contain
+    highlights) to output. The default function prints each line to
+    stdout. Note that the function may be called with multiple lines.
+
+  - $DiffHighlight::flush_cb - this should point to a function which
+    flushes the output (because DiffHighlight believes it has completed
+    processing a logical chunk of input). The default function flushes
+    stdout.
+
+The script may then feed lines, one at a time, to DiffHighlight::handle_line().
+When lines are done processing, they will be fed to $line_cb. Note that
+DiffHighlight may queue up many input lines (to analyze a whole hunk)
+before calling $line_cb. After providing all lines, call
+DiffHighlight::flush() to flush any unprocessed lines.
+
+If you just want to process stdin, DiffHighlight::highlight_stdin()
+is a convenience helper which will loop and flush for you.
