.SH DESCRIPTION
\*(Me is a lightweight and secure socks5 proxy. It is a port of the original
shadowsocks created by clowwindy. \*(Me is written in pure C and takes advantage
of \fBlibev\fP to achieve both high performance and low resource consumption.

requires netfilter's NAT module and \fBiptables\fR(8). For more information,
check out \fBshadowsocks-libev\fR(8) and the following \fBEXAMPLE\fR section.
