+There are two separate user interfaces for PSPP.
+There is the command line interface, which responds to commands
+typed by the user.
+The command line interface is generally available on more platforms
+than the graphic user interface and since it doesn't require a
+graphics device it can be used from a remote terminal.
+Platforms which have a windowing system may also be able to support
+the graphic user interface.
+The graphic user interface can perform all functionality of the
+command line interface.
+In addition it gives an instantaneous view of the data, variables and
+statistical output.
+
+Whichever interface you choose, a basic understanding of the concepts
+used by PSPP is necessary before effective use of the system can be achieved.

Syntax files and output device substitutions can be specified on

A file by itself on the command line will be executed as a syntax file.

+@subsection Input and output options
Input and output options affect how PSPP reads input and writes
output. These are the input and output options:
@table @code
-@item -f @var{file}
-@itemx --out-file=@var{file}
-
-This overrides the output file name for devices designated as listing
-devices. If a file named @var{file} already exists, it is overwritten.
-
-@item -p
-@itemx --pipe
-
-Allows PSPP to be used as a filter by causing the syntax file to be
-read from stdin and output to be written to stdout. Conflicts with the
-@code{-f @var{file}} and @code{--file=@var{file}} options.
-
@item -I-
@itemx --no-include
Appends directory @var{dir} to the path that is searched for include
files in PSPP syntax files.
-@item -c @var{command}
-@itemx --command=@var{command}
-
-Execute literal command @var{command}. The command is executed before
-startup syntax files, if any.
-
@item --testing-mode
Invoke heuristics to assist with testing PSPP. For use by @code{make
check} and similar scripts.

+
+The graphic user interface can be started by typing @command{psppire} at a
+command prompt.
+Alternatively many systems have a system of interactive menus or buttons
+from which @command{psppire} can be started by a series of mouse clicks.
+
+Once the principles of the PSPP system are understood,
+the graphic user interface is designed to be largely intuitive, and
+for this reason is covered only very briefly by this manual.
