.SH DESCRIPTION
.B Ap
is a program that parses addresses according to the ARPA
Internet standard.  It also understands many non\-standard formats.
It is useful for seeing how
.B mmh
will interpret an address.
.PP
The
.B ap
program treats each argument as one or more addresses, and
prints those addresses out in the official 822\-format.  Hence, it is
usually best to enclose each argument in double\-quotes for the shell.
.PP
To override the output format used by
.BR ap ,
the
.B \-form
.I file
switch is used.  This permits individual fields of
the address to be extracted with ease.
The
.I file
is either the name of a format file or it may be
a format string directly, if prepended with an equal sign `='.
See
.BR mh\-format (5)
for the details.
.PP
In addition to the standard escapes,
.B ap
also recognizes the following additional escape:
.PP
.RS 5
.nf
.ta \w'Escape  'u +\w'Returns  'u
.I "Escape	Returns	Description
error	string	A diagnostic if the parse failed
.RE
.fi
.PP
If the
.B \-normalize
switch is given,
.B ap
will try to track down
the official hostname of the address.
.PP
Here is the default format string used by
.BR ap :
.PP
.RS 5
.nf
%<{error}%{error}: %{text}%|%(putstr(proper{text}))%>
.fi
.RE
.PP
which says that if an error was detected, print the error, a `:', and
the address in error.  Otherwise, output the 822\-proper format of
the address.
