+%description
+graftcp can redirect the TCP connection made by the given program [application, script, shell, etc.] to SOCKS5 or HTTP proxy.
+
+Compared with tsocks, proxychains or proxychains-ng, graftcp is not using the LD_PRELOAD trick which only work for dynamically
+linked programs, e.g., applications built by Go can not be hook by proxychains-ng. graftcp can trace or modify any given program's
+connect by ptrace(2), so it is workable for any program. The principle will be explained in this paragraph of how does it work.
