Better written script!

• Using getopts simplifies a lot
• clean-up of the code

If your repo is non-existent, I'll create it

If you gave a path that didn't existed for your repo, then it would go back to the defaults, but it's way better to handle it with a mkdir -p the/path/you/asked/for and that's what I did. ;-)

v2.1.0: armv7l support!

alpine-build-pkg supports armv7l now, too!

v2.0.0 -- EASIER!

Now is way more simpler with just one script and better documentation
and options!

v1.0.0 -- it works!

Working release for the alpine-devel-howto
