Arch tutor - Starting a project

Hacker Muli discovers an O(1) algorithm to calculate prime numbers and starts his ambitious project primes:

mkdir ~/primes
cd ~/primes
# hack primes script
# hack README file

Muli reads that arch is very good and decides to try it. He introduces himself to arch (done once):

tla my-id 'Muli Verner <muli@hacker.org>'
mkdir ~/archives
tla make-archive muli@hacker.org--2004 ~/archives/muli@hacker.org--2004
tla my-default-archive muli@hacker.org--2004

Muli imports a project:

tla archive-setup primes--devel--0
tla init-tree primes--devel--0
tla add README primes
tla import
