LuaRocks vs Maven Central

LuaRocks is a package manager for Lua, with LuaRocks.org hosting rocks and rockspecs for Lua modules. Its command line uses manifests to find packages, choose a version and platform match, and install the corresponding files locally. Rocks carry version dependency information, which LuaRocks uses to install dependencies and load the appropriate module version. Package collections can be organized through the root manifest, per-user manifests, or custom manifests; development versions are kept in a separate manifest and are not installed by default. LuaRocks supports offline installation and platforms including Linux, macOS, Windows, Unix, FreeBSD, and Cygwin. Module authors can register and upload a rockspec, then publish rock files for a version; the current release supports the `luarocks upload` command. The application is described as pure Lua with no library dependencies, though its current release uses helper tools. LuaRocks is free, with a listed price of free.
