# http://crbug.com/62803 tracks the addition of a use_openssl option. Once that bug is closed,
# use_openssl=1 can be passed; dev-libs/{nss,nspr} will no longer be needed. Note that that flag
# currently does not use system openssl but a bundled version from third_party/openssl!
# There is use_system_ssl for that
