# distribute-license.bbclass will search the sources of a package to
# a given depth looking for a match to the specified pattern and if
# found will copy the matching file(s) to the deploy directory.
#
# This class is used to collect license files such as COPYING or
# LICENSE where they are found and save them per package.
#
# This package uses the following variables to control its operations:
# - LICENSE_FILES = Pattern of license files to be searched for.
# By default this is COPYING* and LICENSE* but
# this can be changed per package.
# - LICENSE_SEARCH_DEPTH = The maximum depth to search in the package
# sources for files matching the LICENSE_FILES
# pattern.
# Files to copy for the licensing. By default this is looking for
# files following the patters COPYING* or LICENSING* in the top
# level sources directory.
LICENSE_FILES ?= "COPYING* LICENSE*"
# Maximum depth to look for license files
LICENSE_SEARCH_DEPTH ?= "1"
