Is there a program or a script out there to extract the contents of a Windows installer under Mac Os X?

Under Windows there is the Universal Extractor, I am looking like something like that for Mac. I don't know if there is a universal solution to this problem or if I would need a extractor specific to the type of installer. In my case I am actually trying to get the installer from Gog.com to extract so I can use them with Boxer.

    From the link below: "Many kinds of .exe self-extracting formats are supported. However, if you find one that is not, please post an issue on the bug tracker." There's also support for MSI, NSIS and CAB archives.

    I've had limited luck with 7-Zip. There's a command line version for OS X.

If you have macports, do the following:

sudo port install p7zip
7z x self_extracting_nsis_archive_foo.exe

@user3076105's answer works with Homebrew, too:

brew install p7zip
7z x some_windows_installer.exe

Make sure to put it in a new folder first so it doesn't spew files all over your ~/Downloads directory.

Another tip is that sometimes installers will contain additional installers and you may need to repeat the 7zip extraction command (7z x foo.exe) on some .exe files you find the first time you extract.
