8060 This is a wrapper around the ShellExecute system function, which
8061 invokes the application registered to handle OPERATION for DOCUMENT.
8062
8063 OPERATION is either nil or a string that names a supported operation.
8064 What operations can be used depends on the particular DOCUMENT and its
8065 handler application, but typically it is one of the following common
8066 operations:
8067
8068 \"open\" - open DOCUMENT, which could be a file, a directory, or an
8069 executable program. If it is an application, that
8070 application is launched in the current buffer's default
8071 directory. Otherwise, the application associated with
8072 DOCUMENT is launched in the buffer's default directory.
8073 \"print\" - print DOCUMENT, which must be a file
8074 \"explore\" - start the Windows Explorer on DOCUMENT
8075 \"edit\" - launch an editor and open DOCUMENT for editing; which
8076 editor is launched depends on the association for the
8077 specified DOCUMENT
8078 \"find\" - initiate search starting from DOCUMENT which must specify
8079 a directory
8080 nil - invoke the default OPERATION, or \"open\" if default is
8081 not defined or unavailable
8082
8083 DOCUMENT is typically the name of a document file or a URL, but can
8084 also be a program executable to run, or a directory to open in the
8085 Windows Explorer.
8086
8087 If DOCUMENT is a program executable, the optional third arg PARAMETERS
8088 can be a string containing command line parameters that will be passed
8089 to the program; otherwise, PARAMETERS should be nil or unspecified.
8090
8091 Optional fourth argument SHOW-FLAG can be used to control how the
8092 application will be displayed when it is invoked. If SHOW-FLAG is nil
8093 or unspecified, the application is displayed normally, otherwise it is
8094 an integer representing a ShowWindow flag:
8095
8096 0 - start hidden
8097 1 - start normally
8098 3 - start maximized
