|Recycle Bin Access|

Windows
-------
Recycler API always available: during runtime either SHFileOperation or IFileOperation (since Vista) will be dynamically selected

Linux
-----
Compiler flags: `pkg-config --cflags gio-2.0`
Linker   flags: `pkg-config --libs gio-2.0`

Already included in package "gtk+-2.0"!
