%description
Cloak is a pluggable transport that enhances traditional proxy tools like
OpenVPN to evade sophisticated censorship and data discrimination.

Cloak is not a standalone proxy program. Rather, it works by masquerading
proxied traffic as normal web browsing activities. In contrast to traditional
tools which have very prominent traffic fingerprints and can be blocked by
simple filtering rules, it's very difficult to precisely target Cloak with
little false positives. This increases the collateral damage to censorship
actions as attempts to block Cloak could also damage services the censor
state relies on.
