Winetricks – a helper script to download and install various redistributable runtime libraries needed to run some programs in Wine. These may include replacements for components of Wine using closed source libraries.
It provides simple commands to tweak Wine settings, download and install missing Windows DLLs and fonts, or install various games or apps with appropriate workarounds for the current version of Wine.
It can be used via GUI or command line. The command-line mode is intended both for interactive use and as a building block in fancier Wine frontends and in automated regression testing.
