conan lock

The conan lock command contains several subcommands. In addition to these commands, most of the Conan commands that compute a graph, like create, install, graph, can both receive lockfiles as input and produce lockfiles as output.

• conan lock add: Manually add items to a lockfile

• conan lock remove: Manually remove items from a lockfile

• conan lock create: Evaluates a dependency graph and save a lockfile

• conan lock merge: Merge several existing lockfiles into one

• conan lock update: Manually update items from a lockfile

• conan lock update: (Experimental) Upgrade items from a lockfile

                        requires=pkg/version", but they must be package
                        references, including at least the version, and they
