Cargo Features

[dependencies]
keysim = { version = "0.1.0", default-features = false, features = ["x11"] }
default = x11

The x11 feature is set by default whenever keysim is added without default-features = false somewhere in the dependency tree.

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.
