+#!/bin/bash
+#
+# Simple colorize for bash by means of sed
+#
+# Copyright 2008+2012 by Andreas Schamanek <andreas@schamanek.net>
+# GPL licensed (see end of file) * Use at your own risk!
+#
+# Usage examples:
+#   tail -f somemaillog | mycolorize white '^From: .*' bell
+#   tail -f somemaillog | mycolorize white '^From: \/.*' green 'Folder: .*'
+#   tail -f somemaillog | mycolorize --unbuffered white '^From: .*'
+#
+# Notes:
+#   Regular expressions need to be suitable for _sed --regexp-extended_
+#   Slashes / need no escaping (we use ^A as delimiter).
+#   \/ splits the coloring (similar to procmailrc. Matches behind get color.
+#   Even "white '(for|to) \/(her|him).*$'" works :) Surprisingly ;)
+#   To color the string '\/' use the regular expression '\\()/'.
+#   If the 1st argument is -u or --unbuffered, _sed_ will be run so.
+
+# For the colors see tput(1) and terminfo(5), or e.g.
