# 升级到官方 release-2.1.13-stable，并补齐 RNOH 0.72.143 源码构建所需的 jsi.cpp 链接项。
#
# 用法（在跑完 `ohpm install --all` 之后、`hvigorw` 编译之前执行一次）：
#   bash ohos/scripts/patch-libevent-2113.sh <harmony 工程根目录，如 ohos/example/harmony>
#
# 原理见 ohos/scripts/README-libevent-2113-patch.md。脚本本身不下载任何东西——
# libevent 2.1.13-stable 源码树已经作为小体积文件提交在 ohos/vendor/libevent-2.1.13-src/，
# 不依赖网络访问（构建机可能无法访问 github）。
