# A nawk/gawk script used to extract the application's platform name from
# its project.properties file. It is called from build/core/add-application.mk
#

# we look for a line that looks like one of:
#    target=android-<api>
#    target=<vendor>:<name>:<api>
#
# <api> is a number, but can also be "Donut" for the first form,
# as a special case.
