Puppy 5.2 uses unique Puppy scripts. Puppy loads and runs fast entirely from Ram. Puppy has optimised programs and wizards.

Puppy 5.2 uses Puppy 'Woof' creation technology Puppy Woof allows Puppy to be partially built from Debian and Ubuntu compiled programs and libraries. Puppy 5.2 retains the name 'Puppy Lucid' but uses 10.10 binaries from Maverick Meerkat.

Using Woof, Puppy can be built with packages from almost any distro.

All the underlying infrastructure and boot scripts; basically everything that makes Puppy unique, is in Woof. Above Woof, there is a layer of specialised system-level PETs that we have created ourselves. The scripts vary in different Puppy builds. Lucid Puppy has special system-level PETs, which contribute to making Lucid different from other Puppys built from Woof.

A Puppy can be built with packages of any other distro, as well as our own native PET application packages. Lucid Puppy 5.2 is built with Ubuntu packages, about 60% Ubuntu, 40% our PETs. Applications go on top of Woof and the system-level PET's.

Puppy can be built from almost any other distro's packages also, including Debian, Slackware and Arch.

Internal development used the name 'Luci'. So for example a download is called luci-242.
