[phobos] What's the deal with changelog.dd?

[Andrei Alexandrescu]

I'm seeing a changelog.dd in phobos, which seems to be a fragment only 
intended for inclusion in a larger changelog:

https://github.com/D-Programming-Language/phobos/blob/master/changelog.dd

Also, there is the large changelog in d-programming-language.org:

https://github.com/D-Programming-Language/d-programming-language.org/blob/master/changelog.dd

How is the setup meant to be used? My hypothesis is that there's a 
script somewhere that prepends phobos/changelog.dd to 
d-programming-language.org upon each release. Is that correct? If so, 
how do we update the changelog? Is it time to simply remove everything 
for 2.053 and start the changelog for 2.054?


Thanks,

Andrei
