+Get Windows to perform OPERATION on DOCUMENT.
+This is a wrapper around the ShellExecute system function, which
+invokes the application registered to handle OPERATION for DOCUMENT.
+OPERATION is typically \"open\", \"print\" or \"explore\" (but can be
+nil for the default action), and DOCUMENT is typically the name of a
+document file or URL, but can also be a program executable to run or
+a directory to open in the Windows Explorer.
+
+If DOCUMENT is a program executable, PARAMETERS can be a string
+containing command line parameters, but otherwise should be nil.
+
+SHOW-FLAG can be used to control whether the invoked application is hidden
+or minimized.  If SHOW-FLAG is nil, the application is displayed normally,
+otherwise it is an integer representing a ShowWindow flag:
+
+  0 - start hidden
+  1 - start normally
+  3 - start maximized
+  6 - start minimized
