That'll tell you the name of the executable, but the path is relative to the 
directory that the program was run from. However, if you combine that with 
std.path.absolutePath, you should be able to get the absolute path to the 
executable, and from that you should be able to get the directory with 
std.path.dirName.

Alternatively, if you want to know the current working directory, then use 
std.file.getcwd.
