Answer:

com/conan-io/conan 2.2 Decentralized package manager Conan is a decentralized package manager with a client-server architecture. This means that clients can fetch packages from, as well as upload packages created by the client, and if binaries are built from sources, that compilation is also done by the client application. The different applications in the image above are: • The conan client: this is a console/terminal command line application, containing the heavy logic for package creation and consumption. Conan client has a local cache for package storage, and so it allows you to fully create and test packages offline
