+Creating a cc-cmd (and to-cmd) action
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+git-send-email invokes the cc-cmd like this:
+
+	$cc-cmd $patchfilename
+
+Thus the patch itself can be processed to locate appropriate email address
+information if required.
+
+A simple solution for a basic address list is to create a 'cc-cmd' file
+(executable) which provides a list of addressees:
+
+	#!/bin/sh
+	echo <<\EOF
+	person1@example.com
+	person2@example.com
+	EOF
+
+Simply, using `cat cc-cmd` as the --cc-cmd (with cc-cmd as the text file
+of email addresses), does not work as expected as the invocation becomes:
+
+	$cat cc-cmd $patchfilename
+
+and since 'cat' copies the concatenation of its input files to its output,
+this adds the patch file to the address list resulting in an error
+"unable to extract a valid address from:".
+
+The quick-and-dirty work-around is to use '#' to effectively comment out
+the patch file name:
+
+    --cc-cmd='cat cc-cmd #'
+
+which works, but is very, very ugly.
