dmd.conf... again

[Dicebot via Digitalmars-d-learn]

More info about what gets placed where please.

I have special dev layout on my system that co-exists with 
system-wide installation of dmd. It is as simple as having 
~/dlang/{dmd|druntime|phobos}, linking ~/dlang/dmd/src/dmd to 
~/bin/dmd-dev and placing dmd.conf in ~/bin which adds all those 
paths as -I and -L flags. Works just fine.
