Do you accept contributions to the cryptsetup manpage via patch sent by

Hi,
sure, you can send it by email (either to this list or to me directly).
Hi,
You'll find the manpage patch attached.
I've renamed "BASIC COMMANDS" to "BASIC ACTIONS" because the commands
are called action in the SYNOPSIS, too. Furthermore I changed a sentence
saying that luksFormat would work on unmapped luks containers, only. And
last but not least I've added the Section "EXAMPLE" with six examples of
common use cases.
Please, let me know what you think about the patch and whether you are
going to merge it.
Regards,
Joerg
