The first step to using arch is to set your id with a command like:
% tla my-id "Tom Lord <firstname.lastname@example.org>"
Your id should be your name, followed by your email address in angle brackets.
arch records your id in various log messages that it creates.
You can find out your id with:
% tla my-id Tom Lord <email@example.com>
After the command above, you will have some new files in your home directory:
% ls ~/.arch-params =id % cat ~/.arch-params/=id Tom Lord <firstname.lastname@example.org>
Caution: You usually should not edit files in
