according to some comments in the shell script: Winetricks is a package
manager for Win32 dlls and applications on POSIX.
Can I build such Win32 dlls with tools available in Debian main?
Can I build the Win32 applications with tools available in Debian main?
I think the answer to both questions is "no", so the main purpose of winetricks
is to download something that can not be part of Debian main and such the
package belongs to contrib.
then what is src:gcc-mingw-w64 for if not to build win32 libraries and
executables?
