It is an APT repository (not sure what the technical term is, but I'm
sure you understand the meaning) maintained outside of Debian "to make
all Tryton releases available for the different Debian suites
[outside] the main repository of Debian. [...] Note: Those packages
are unofficial and you are using them at your own risk (as always)."
