This is an example of setting the clipboard using the Windows API 
in D:
```
/// Returns: true on success
bool setClipboard(string str) {
	import core.stdc.string: memcpy;
	import std.string: toStringz;
	import core.sys.windows.windows: GlobalAlloc, GlobalLock, 
GlobalUnlock,
		OpenClipboard, EmptyClipboard, SetClipboardData, CloseClipboard,
		CF_TEXT, CF_UNICODETEXT, GMEM_MOVEABLE;
		
	auto hMem = GlobalAlloc(GMEM_MOVEABLE, str.length + 1);
	if (hMem is null) {
		return false;
	}
	memcpy(GlobalLock(hMem), str.ptr, str.length);
	(cast(char*) hMem)[str.length] = '\0'; // zero terminator
	GlobalUnlock(hMem);
	if (!OpenClipboard(null)) {
		return false;
	}
	EmptyClipboard();
	if (!SetClipboardData(CF_TEXT, hMem)) {
		return false;
	}
	CloseClipboard();
	return true;
}
```

Here's an example of getting it, from arsd:

Here is a C example from GLFW:

Thanks a lot. Well, i thought it should be a one liner like-
Clipboard.SetText(sText)
But after reading your reply, i realized that this is D, not a 
scripting language. :)

It would be a one-liner if it was an api. Such utility APIs are 
quite missing in D.

How about putting them together into a package?

Um, You are right.

Well, this is an inspiration to me. Let me try. :)
