This file defines
layers,
which are directory trees, traversed (or walked) by BitBake.
If bblayers.conf
is not present, it is created from bblayers.conf.sample
when
you source
the environment setup script.
The bblayers.conf
file uses the
BBLAYERS
variable to
list the layers BitBake tries to find.
The file uses the
BBLAYERS_NON_REMOVABLE
variable to list layers that must not be removed.
