Cargo Features

[dependencies]
lc3asm = { version = "0.1.2", features = ["binary-build"] }
binary-build = 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.
