This script can be used directly from poky, or can be copied directly into a
layer or any other repository - it is self-suffucient and requires only python3
and git on the host where it will run. It is also copied by the bitbake-layers
layers-setup plugin together with the json, unless requested otherwise.
1. How to restore the layers from the saved configuration:
a) Clone the bootstrap layer or some other repository to obtain the json config
and the setup script that can use it.
(use 'bitbake-layers create-layer-setup' from the previous commit to create
them)
b) Running with default options:
(note: this will work to update an existing checkout as well)
alex@Zen2:/srv/work/alex/my-build$ meta-alex/setup-layers
Note: not checking out source meta-alex, use --force-bootstraplayer-checkout to
override.

alex@Zen2:/srv/work/alex/my-build$ meta-alex/setup-layers -h
usage: setup-layers [-h] [--force-bootstraplayer-checkout] [--destdir DESTDIR]
[--jsondata JSONDATA]
A self contained python script that fetches all the needed layers and sets them
to correct revisions
optional arguments:
-h, --help show this help message and exit
--force-bootstraplayer-checkout
Force the checkout of the layer containing this file
(by default it is presumed that as this script is in it, the layer is already
in place).
--destdir DESTDIR Where to check out the layers (default is
/srv/work/alex/my-build).
--jsondata JSONDATA File containing the layer data in json format (default
is /srv/work/alex/my-build/meta-alex/setup-layers.json).
