Generating DDOX documentation

[Andrew Edwards via Digitalmars-d-learn]

Given a documented source file (eg. process.d), I can generate 
the DDOC version of the documentation with the -D switch of DMD 
as such:

    $ dmd -Dfprocess.html process.d
What do I modify on that line to get the DDOX version of the same 
file?

Thanks,
Andrew
