Browsing D compiler source code

[Walter Bright via Digitalmars-d]

The recent conversion of the D compiler source code opens up the practicality of 
using Ddoc on the code. Like the Phobos Ddoc output is browsable on dlang.org, 
the D compiler source should be, too. It also provides an incentive to properly 
document the compiler source code, and improve tools that use Ddoc to cross 
reference and otherwise analyze D source code.

Anyone want to take this on? It shouldn't be hard, pretty much just copy what is 
done to make the Phobos docs online.
