A separate patch to base.bbclass (in poky) will add the OE_EXTRA_IMPORTS
variable. The contents are appended into OE_IMPORTS. This provides a
mechanism by which layers (in their layer.conf) can make custom progress
handlers available.
As a backup, individual recipes can inject progress handlers into
__builtins__.
Custom handlers are expected to have this __init__ signature:
def __init__(self, d, outfile=None, otherargs=None):
Recipes can then use the handlers like this:
do_task[progress] = "custom:mylayer.util.ProgressHandler[:args]"
The last part (everything after and including the second colon) is
optional. If provided, it is passed to HandlerClass's __init__ as
otherargs="args". Otherwise, otherargs=None.

Bitbake
BitBake is a generic task execution engine that allows shell and Python tasks to be run efficiently and in parallel while working within complex inter-task dependency constraints. One of BitBake's main users, OpenEmbedded, takes this core and builds embedded Linux software stacks using a task-oriented approach.
For information about Bitbake, see the OpenEmbedded website: http://www.openembedded.org/
Bitbake plain documentation can be found under the doc directory or its integrated html version at the Yocto Project website: http://yoctoproject.org/documentation
Contributing
Please refer to http://www.openembedded.org/wiki/How_to_submit_a_patch_to_OpenEmbedded for guidelines on how to submit patches, just note that the latter documentation is intended for OpenEmbedded (and its core) not bitbake patches (bitbake-devel@lists.openembedded.org) but in general main guidelines apply. Once the commit(s) have been created, the way to send the patch is through git-send-email. For example, to send the last commit (HEAD) on current branch, type:
git send-email -M -1 --to bitbake-devel@lists.openembedded.org
