 # oe-git-proxy is a simple tool to be via GIT_PROXY_COMMAND. It uses socat
-# to make SOCKS5 or HTTPS proxy connections. It uses ALL_PROXY to determine the
-# proxy server, protocol, and port. It uses NO_PROXY to skip using the proxy for
-# a comma delimited list of hosts, host globs (*.example.com), IPs, or CIDR
-# masks (192.168.1.0/24). It is known to work with both bash and dash shells.
