Additional information
Tool currently being tested and written
Scytale is currently being tested and written.
A cleaner, clearer and more polished version will arrive on the site soon. It will replace this temporary block with notes that match the actual behavior of the tool.
Until then, you can use the tool interface, keeping in mind that its presentation and explanations may still evolve.
