Macpup Opera adds a little sizzle to Puppy's minimalist core
If you're an Opera fan and a Linux experimenter, this distro is a double win for you. As you'd guess from the full name, Opera (9.64) is baked in. SeaMonkey is also included, and other browsers are just a repository away. MacPup bundles additional programs for just about every common task, including apps like Transmission, Gnumeric, AbiWord, Gxine, and Xfburn.
Enlightenment e17 handles window management duties, so you can skin your desktop with any of the themes available at Get-E.org to customize your experience.
Since it's Puppy-based, you can roll-your-own distro using Remaster once you have things configured the way you want and burn your creation to a CD or write it to a USB flash drive.
Macpup runs beautifully on minimal hardware and it's an excellent distribution for older machines. Even in a VirtualBox VM running 384Mb memory, performance was solid - especially after installing to the virtual hard drive.
