systemd service file and management scripts for manually deploying PeerBanHelper

[poplar-at-twilight]

基于 systemd --user，适用于 PeerBanHelper 的管理脚本、systemd 服务文件和测试脚本如下所示：
Based on systemd --user, the administrative scripts, systemd service files and test scripts for PeerBanHelper are shown below:

管理脚本 - Management Scripts

注意，解压文件时使用的外部命令是 7z，它由 ark 归档管理器依赖的 7zip 所提供。
Note that the external command used to decompress the file is 7z, which is provided by 7zip, which the ark archive manager depends on.

本来想试试deb包，结果发现完全找不到data文件路径的说明。

本来想试试deb包，结果发现完全找不到data文件路径的说明。

你可以通过查看 deb 软件包内的文件确定 data 目录位置（-Dpbh.datadir=/etc/peerbanhelper）：
