Cargo Features

[dependencies]
pwntools = { version = "0.4.0", default-features = false, features = ["use-unicorn"] }
default = use-unicorn

The use-unicorn feature is set by default whenever pwntools is added without default-features = false somewhere in the dependency tree.

use-unicorn default = unicorn-engine

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
