anchor.diff:  === Adding Commands
   To add a NiFi command, create a new class that extends `AbstractNiFiCommand`:
   
  -```
  +[source]
  +----
   public class MyCommand extends AbstractNiFiCommand {
   
     public MyCommand() {
  
positive.code:        <property name="TLS - Keystore Type"></property>
         ...
     </userGroupProvider>
  ```
  
  == File Manager
  The File Manager utility (invoked as `./bin/file-manager.sh` or `bin\file-manager.bat`) allows system administrators to take a backup of an existing NiFi installation, install a new version of NiFi in a designated location (while migrating any previous configuration settings) or restore an installation from a previous backup. File Manager supports NiFi version 1.0.0 and higher.
  
negative.code:   * If the `-o` argument is not provided, the default working directory (`.`) must contain `nifi-cert.pem` and `nifi-key.key`
    ** e.g. `$ cd ./hardcoded/ && ../toolkit/bin/tls-toolkit.sh standalone -n 'node5.nifi.apache.org' -P thisIsABadPassword -S thisIsABadPassword -O`
