Cargo Features

cargo-sync-readme = { version = "1.1.0", default-features = false, features = ["cli"] }
default = cli

The cli feature is set by default whenever cargo-sync-readme is added without default-features = false somewhere in the dependency tree.

cli default = structopt

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.
