.uue - which stands for unified utility engine (and sometimes simply referred to as The Dot or Lnq's Concerto), is the generic and default format for all things UUe-related; namely that of jukebox cassette distribution.
.uue is constructed for handling complete Egglepple-compatibility.
This container format is device-agnostic whose declarations (reads and calls) are represented independently. Binarily threaded, a .uue element mimics string as an arbitrary array - acting as a composite archive by allocating data into prologue and epilogue register divisions.
Note (+): .uue is the manifest file suffix.
