tool: D9: USAGE: tagger [OPTION] OPERATION [PARAMETERS]

tool: D1: Try 'tagger --help' for more information.

tool: D23: OPTIONS:
  --mode=           Specify on which elements operation is to apply
                    Possible values: 'tags|'files'

                    Default: 'home'
  --env-dir=        Force using a specific name for database folder
                    Default '.tagger'
  --local           Force using current directory for database

  --trash           Restrict current operation to trashed elements only
  --db-charset=     Specify database charset (default is UTF-8)
  --db-node-syntax= Define how filenames are stored (relative or absolute path)

  --debug           Output program trace and internal errors
  --help            Display this help text
  --version         Display version information

tool: D0: OPERATIONS:
  init          Setup tagger environment (create an empty database)
  create        Create one or more new tag(s)
  clone         Create a new element by copying all relations from another
  delete        Delete one or more element(s) (all relations will be lost)

  list          Show all elements in database for specified mode
  query         Retrieve all elements matching given criteria (depends on mode)
  tags          Shorthand for "tagger --tags list"
  files         Shorthand for "tagger --files list"

tool: D58: Examples:
