    Usage
      $ express-router-dependency-graph [input]
 
    Options
      --cwd                   [Path:String] current working directory. Default: process.cwd()
      --rootBaseUrl           [Path:String] if pass it, replace rootDir with rootDirBaseURL in output.
      --format                ["json" | "markdown"] output format. Default: markdown

    Examples
      # analyze all ts files in src directory
      $ express-router-dependency-graph "src/**/*.ts"
      # analyze all ts files in src directory and output json
      $ express-router-dependency-graph "src/**/*.ts" --format=json
      # analyze all js and ts files in src directory
      $ express-router-dependency-graph "src/**/*.ts" "src/**/*.js"
      # change base url of output
      $ express-router-dependency-graph "src/**/*.ts" --rootBaseUrl="https://github.com/owner/repo/tree/master/src"
      # include node_modules
      # ${JSON.stringify(defaultExcludes)} is excluded by default
