-16-bit and 32-bit DOS and Windows applications may be executed. However,
-redirection and piping of standard IO only works with 16-bit DOS
-applications. 32-bit applications always see standard input as already
-closed, and any standard output or error is discarded, no matter where in the
-pipeline the application occurs or what redirection symbols are used by the
-caller. Additionally, for 16-bit applications, standard error is always
-sent to the same place as standard output; it cannot be redirected to a
-separate location. In order to achieve pseudo-redirection for 32-bit
-applications, the 32-bit application must instead be written to take command
-line arguments that specify the files that it should read from and write to
-and open those files itself.
-.sp
-All applications, both 16-bit and 32-bit, run synchronously; each application
-runs to completion before the next one in the pipeline starts. Temporary files
-are used to simulate piping between applications. The \fBexec\fR
-command cannot be used to start an application in the background.
-.sp
-When standard input is redirected from an open file using the
-``\fB@\0\fIfileId\fR'' notation, the open file is completely read up to its
-end. This is slightly different than under Windows 95 or NT, where the child
-application consumes from the open file only as much as it wants.
-Redirecting to an open file is supported as normal.
