Cargo Features

[dependencies]
untree = { version = "0.10.0", default-features = false, features = ["build-binary"] }

Building the binary requires clap

default = build-binary

The build-binary feature is set by default whenever untree is added without default-features = false somewhere in the dependency tree.

build-binary 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.
