There are different type of layouts. First the *new* standard layout used by gutsy firefox/thunderbird/firefox-granparadiso and later others:

{{{
Setup your main working directory
==================================
#1 go to your bzr work directory (for me i created a directory: $HOME/mozillateam_bzr)
cd $HOME/mozillateam_bzr

#2 OPTIONAL: initialize that directory as a bzr repository:
bzr init-repo .

#3 create a tarballs/ directory, like
mkdir tarballs


Use-Case: Create new orig.tar.gz from upstream tarball
========================================================

# create a directory called packagename-UPSTREAM.VERSION, e.g.
mkdir midbrowser-0.1~daily070730/

# put in the upstream tarball
cp /tmp/midbrowser-0.1~daily070730-source.tar.bz2 midbrowser-0.1~daily070730/

# tar it up as a new orig:
tar cvzf tarballs/midbrowser_0.1~daily070730.orig.tar.gz midbrowser-0.1~daily070730/


Build from bzr
===============

#1 ensure you are in your main bzr work dir
cd $HOME/mozillateam_bzr

#2 checkout a bzr branch:
bzr branch http://bazaar.launchpad.net/~ubuntu-mobile/midbrowser/ubuntu midbrowser.ubuntu 

#3 build bzr branch:
cd midbrowser.ubuntu/; bzr bd --merge .

#4 look at results in $HOME/mozillateam_bzr/build-area ... and install .debs etc. from there
cd $HOME/mozillateam_bzr/build-area

}}}


*** Commands to build Iceape/Seamonkey ***
{{{
#0 Grab from bzr
bzr clone http://bazaar.launchpad.net/~mozillateam/iceape/ubuntu-1.1.x

#1 Update from branch
