import std.stdio;
void main (string[] args)

writeln(args[0]);

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.

This way won't work. main's args[0] (which also is
Runtime.args[0]) only tells you the executed command line.
Suppose on Windows there is an exe file(foo.EXE) in a
dir(C:\bar), which is in %PATH%. Call "foo" anywhere(CWD==D:\),
then C:\bar\foo.EXE will be executed, and its args[0] will be
just "foo". Because absolutePath(args[0]) uses getcwd by default,
so "D:\foo"(getcwd~args[0]) will be incorrectly got.
