Hi,
I was trying bazaar.

These are the steps I did, can you check if I did everything correctly?

- I have created an account on launchpad and uploaded an ssh key (on
my home page, -> click on 'Profile', then 'Edit details', and then
'Ssh keys' - it costed me a bit to find it at first :) ).

- On my computer, from a terminal, I have executed
"bzr-launchpad-login <my username>" to login to launchpad.

- I ran "bzr branch lp:~bartek/junk/biopython", to create a branch of
your repository in my computer.

- I did some stupid changes (I must have messed a bit with creating
branches), and then committed them.

So now, if I want to inform you of the changes I have made, how does
it work? Which is the correct bazaar command to pull a merge request?

- In the meantime, I have created an entry for my branch on launchpad.
I went to my home page, clicked on 'Code', and then 'Register a new branch'.
On the 'Reference Project' field, I couldn't find your project, only
the biopython created a few years ago of which you were asking
earlier.

This is my branch:
- https://code.launchpad.net/~dalloliogm-gmail/+junk/biopython-gio

How do I link it to your repo, now?
