Constant Summary collapse

Endpoint = 
%{
  The endpoint may be one of:
  * directory -- absolute or relative local directory (/data, ../source, c:\\data)
  * local:directory, :directory -- absolute local directory (:/data, local:c:\\data)
  * :tag:directory -- path relative to the intact volume matched by (partial) tag (:fa2c:source/data)

  The former case resolves specified directory againt an intact volume to make it volume-relative.
  It is an error if there is no intact volume that encompasses specified directory.
  The local: directory is left as is (not resolved against volumes).
  The :tag: directory is bound to the specified volume.
}
Encryption = 
%{
  The encryption mode is controlled by --encrypt or --decrypt options.
  The mandatory password will be read from the standard input channel (pipe or keyboard).
}
