Cargo Features

quickcfg = { version = "0.6.3", default-features = false, features = ["git2"] }
default = git2

The git2 feature is set by default whenever quickcfg 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.
