# The rate plugins create some symlinks. For example, the samplerate plugin
# creates these links to the main plugin file:
#
#   libasound_module_rate_samplerate_best.so
#   libasound_module_rate_samplerate_linear.so
#   libasound_module_rate_samplerate_medium.so
#   libasound_module_rate_samplerate_order.so
#
# The other rate plugins create similar links. We have to add the links to
# FILES manually, because do_split_packages() skips the links (which is good,
# because we wouldn't want do_split_packages() to create separate packages for
# the symlinks).
#
# The symlinks cause QA errors, because usually it's a bug if a non
# -dev/-dbg/-nativesdk package contains links to .so files, but in this case
# the errors are false positives, so we disable the QA checks.
