## Private Attributes

pile | stack
| the different layer through which the archive contents is read or wrote
header_version | ver
| information for the archive header
catalogue * | cat
| archive contents
infinint | local_cat_size
| size of the catalogue on disk
bool | exploitable
| is false if only the catalogue is available (for reference backup or isolation).
bool | lax_read_mode
| whether the archive has been openned in lax mode (unused for creation/merging/isolation)
bool | sequential_read
| whether the archive is read in sequential mode
std::list< signator > | gnupg_signed
| list of signature found in the archive (reading an existing archive)
slice_layout | slices
| slice layout, archive is not sliced <=> first_size or other_size fields are set to zero (in practice both are set to zero, but one being set is enought to determine the archive is not sliced)
