It also understands many non-standard formats. It is useful for seeing how MH will interpret an address. .PP The .PN ap program treats each argument as one or more addresses, and prints those addresses in the official RFC 822 format. Hence, it is usually best to enclose each argument in double quotes (") for the shell. .PP In addition to the standard escapes, .PN scan also recognizes the additional escape \f(CWerror\fR, which is a diagnostic that is returned if the parse failed. .\" .\" .\" .\" .SH Options .IP "\-form \fIfile\fB" 10 Overrides the default output format of .PN ap .

The output is formatted according to the instructions in the specified string.
