The unsigned int 'option' is forwarded to GetDataSet and BrowseDataSet. Available options (to be .or.ed): kShowDefault a default selection is shown that include the ones from the current user, the ones from the group and the common ones kPrint print the dataset content kQuotaUpdate update quotas kExport use export naming
NB1: options "kPrint", "kQuoatUpdate" and "kExport" are mutually exclusive NB2: for options "kPrint" and "kQuoatUpdate" return is null.

Parse the input string and set the init bits accordingly Format is dir:<datasetdir> [mss:<mss-url>] [opt:<base-options>] The <datasetdir> is mandatory.
See TDataSetManager::ParseInitOpts for the available base options. The base options are already initialized by the base constructor

Register a dataset, perfoming quota checkings and verification, if required.
If a dataset with the same name already exists the action fails unless 'opts' contains 'O', in which case the old dataset is overwritten, or contains 'U', in which case 'newDataSet' is added to the existing dataset (duplications are ignored, if any). If 'opts' contains 'V' the dataset files are also verified (if the dataset manager is configured to allow so). By default the dataset is not verified. If 'opts' contains 'T' the in the dataset object (status bits, meta,...) is trusted, i.e. not reset (if the dataset manager is configured to allow so). Returns 0 on success, -1 on failure

Writes indicated dataset.
If option has the bit kFileMustExist set, the file must still exist, otherwise the new dataset is not written (returns 3 in this case). If checksum is non-zero the files current checksum is checked against it, if it does not match the file is not written (the function returns 2 in this case, if the file has disappeared it is also not written (i.e. checksum implies the bit kFileMustExist set in option). Returns != 0 for success, 0 for error
