Yet another project that can't build a website that says anything unless javascript is enabled. Also, yet another project that can't explain what it's about without assuming the reader knows all about another project. So what I take from this is just a guess but it's a development system for a development and/or packaging system that, like too many others, depends on taking the familiar, well understood - by some of us - Unix-style file system and rearranging it.
To which I can only respond by quoting two well-known sources:
"Oh no, not again" (Bowl of petunias)
"The great thing about standards is there so many of them to choose from" (Tannenbaum)
