+We don't require copyright assignment or any fancy paperwork!  Just
+make sure you specify the license and include a copyright statement
+with your name and the current year.
+
+New code should (please) be licensed GPLv2+.  I say v2 instead of v3
+because some code from Arch is GPLv2 (no "or any later version"), and
+having to worry about which programs can be combined is a huge pain.
+
+Copyright statements should look like
+
+	# Copyright (C) YEARS NAME <EMAIL>
+
+for most code, for 3rd-party code that has been imported, indent it a
+bit:
+
+	#   Copyright (C) YEARS NAME <EMAIL>
+
+Always put a line with `# License:` specifying the license of that
+file.
