Auto-detect proxy switcher in terminal. It supports many protocols and tools.

---

Overview

A smart proxy switcher wrapper, supports http, https, ftp, rsync, ssh(connect depended), git(connect depended) protocols.

It can automatically detect your network environment (in preset set) and fit proxy for you.

It supports multi-proxies.

If you usually switch the network environment (maybe home with no-proxy, workplace1 with proxy1, workplace2 with proxy2), it may help you a lot.

Tested in Zsh and Bash on Linux and Mac.
