// cell add <locator> [alias] - Add a dependency to the current package
//
// Usage:
//   cell add <locator>         Add a dependency using default alias
//   cell add <locator> <alias> Add a dependency with custom alias
//   cell add -r <directory>    Recursively find and add all packages in directory
//
// This adds the dependency to cell.toml and installs it to the shop.
