Cargo Features

[dependencies]
in-container = { version = "1.1.0", default-features = false, features = ["exe"] }
default = exe

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

exe default = clap

Required by the binary

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.
