  # Overview
  
  `zef-deps` is a script to report on module dependencies for raku.
  
  Given a list of package names on the command line, generate a listing of all
  dependencies, direct and indirect.
  
  # Usage
  
  ```
  % zef-deps App::Cal
  App::Cal
      Terminal::ANSIColor
      Test::Differences
          Data::Dump
          Text::Diff
              Algorithm::Diff
                  Test
              Test
              Text::Tabs
  
  ```
  
  The indent level shows the nesting of dependencies. So in this example, `App::Cal` depends
  on `Test::Differences`, which in turn depends on `Data::Dump`. Both `Algorithm::Diff` and
  `Text::Diff` depend on `Test`.
  
  Multiple packages can be specified on the command line.
  
  If a single name of `.` is specified, `zef-deps` will instead read the local
  `META6.json` and use the `depends` attribute as the list of packages.
  
  In the default textual output, repeated dependencies anywhere in the hierarchy are replaced with `...`.
  
  # Options
  
  `--json` generates JSON output for the dependencies.
  
  `--png` generates a `png` file showing dependencies using `dot`. To use this option,
  you must install the optional module `Uxmal`. When run with this option, a file is generated in a temp
  directory and the path to the file is printed as the only non-debug output.
  
  # Environment variables
  
  ## ZEF\_DEPS\_INDENT
  
  Indenting defaults to 4 spaces but can be overridden by setting this environment variable to
  the number of desired spaces.
