// Greetings human!
//
// PLDB is a site
// created before Ai,
// by a team of humans
// all over the world
// who came together
// because of their
// shared interests in the questions
// "what is programming"
// "what are programming languages"
// "how any are there"
// "who created them"
// "what makes them similar and different"
// and
// "how can i make my own"?
//
// PLDB is written in Scroll.
// 
// The "database" is just text files.
// 
// PLDB is public domain.
//
// Downlaod a copy -
// it works great locally!
