+============================
+
+This minor node describes a ‘gawk’-specific feature.
+
+   Normally, when you send data down a pipeline to a command with
+‘print’ or ‘printf’, ‘gawk’ “flushes” the output down the 
pipe.  That
+is, output is not buffered, but written directly.  This assures, that
+pipeline output intermixed with ‘gawk’’s output comes out in the
+expected order:
+
+     print "something"                 # goes to standard output
+     print "someting else" | "some-command"    # also to standard output
+     print "more stuff"                        # and this too
+
+   There can be a price to pay for this; flushing data down the pipeline
+uses more CPU time, and in certain environments this can become
+expensive.
+
+   You can tell ‘gawk’ not to flush buffered data in one of two ways:
+
+   • Set ‘PROCINFO["BUFFERPIPE"]’ to any value.  When this is done,
+     ‘gawk’ will buffer data for all pipelines.
+
+   • Set ‘PROCINFO["COMMAND", "BUFFERPIPE"]’ to any value.  In this
+     case, only COMMAND’s data will be fully buffered.
+
+   You _must_ create one or the other of these elements in ‘PROCINFO’
+before the first ‘print’ or ‘printf’ to the pipeline.  Doing so after
+output has already been sent is too late.
+
+   Be aware that using this feature may change the output behavior of
+your programs, so exercise caution.

+@section Speeding Up Pipe Output
+@c FIXME: Add indexing
+
+This @value{SECTION} describes a @command{gawk}-specific feature.
+
+Normally, when you send data down a pipeline to a command with
+@code{print} or @code{printf}, @command{gawk} @dfn{flushes} the
+output down the pipe. That is, output is not buffered, but
+written directly.  This assures, that pipeline output
+intermixed with @command{gawk}'s output comes out in the
+expected order:
+
+@example
+print "something"                      # goes to standard output
+print "someting else" | "some-command" # also to standard output
+print "more stuff"                     # and this too
+@end example
+
+There can be a price to pay for this; flushing data down
+the pipeline uses more CPU time, and in certain environments
+this can become expensive.
+
+You can tell @command{gawk} not to flush buffered data in
+one of two ways:
+
+@itemize @bullet
+@item
+Set @code{PROCINFO["BUFFERPIPE"]} to any value. When this is done,
+@command{gawk} will buffer data for all pipelines.
+
+@item
+Set @code{PROCINFO["@var{command}", "BUFFERPIPE"]} to any value.
+In this case, only @var{command}'s data will be fully buffered.
+@end itemize
+
+You @emph{must} create one or the other of these elements
+in @code{PROCINFO} before the first @code{print} or
+@code{printf} to the pipeline.  Doing so after output has
+already been sent is too late.
+
+Be aware that using this feature may change the output behavior of
+your programs, so exercise caution.
