You will also have to search the path to find it. argv[0] seems to be 
whatever you used to call the program put something on the path and run 
it without a full path you will get the name you typed in


<code name="test.d">
import std.stdio;
void main(char[][] argv){foreach(i,a;argv)writef("%d:>\"%s\"\n",i,a);}
</code>

// put in path at /bin/foo/
$test
0:>"test"

// call directly
$/bin/foo/test
0:>"/bin/foo/test"

// call locally
$./test
0:>"./test"

Seems to be a direct mapping to whater exec was given.
