+.PP
+The \*(lqformat\*(rq flag specifies that this component will be run through
+the filter program specified by the
+.IR formatproc
+profile entry. This filter program is expected to read data on standard
+input and output data on standard output. Currently the \*(lqformat\*(rq
+flag is only supported for the \(*lqbody\*(rq component. The component
+name will be prefixed to the output
+.IR after
+the filter has been run. The expected use of this is to filter a message
+body to create more pleasing text to use in a reply message.
+A suggested filter to use for
+.BR repl(1)
+is as follows:
+.PP
+.RS 5
+body:component=">",overflowtext=">",overflowoffset=0,format,nowrap
