DESCRIPTION
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 nmh will interpret an address.
The 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.
To override the output format used by ap, the `-format\ string' or
`-format\ file' switches are used. This permits individual fields of
the address to be extracted with ease. The string is simply a format
string, and the file is simply a format file. See mh-format\0(5)
for the details.
In addition to the standard escapes,
ap also recognizes the following additional escape:
\w'Escape 'u +\w'Returns 'u
Escape Returns Description
error string A diagnostic if the parse failed
If the `-normalize' switch is given, ap will try to track down
the official hostname of the address.
Here is the default format string used by ap:
%<{error}%{error}: %{text}%|%(putstr(proper{text}))%>
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.

`-format' defaults as described above
`-normalize'
`-width' defaults to the width of the terminal
None
The argument to the `-format' switch must be interpreted as a single token
by the shell that invokes ap.
Therefore,
one must usually place the argument to this switch inside double-quotes.
