+The @command{from} utility displays sender and subject of each message
+in a mailbox. By default, it reads the user's system mailbox. If the
+program is given a single argument, it is interpreted as a user
+name whose mailbox is to be read. Obviously, permissions are required
+to access that user's mailbox, so such invocations may be used only
+by superuser.
+
+Option @option{-f} (@option{--file}) instructs the program to read
+the given mailbox.
+
+The full list of options, supported by @command{from} follows:
+
+@table @option
+@item -c
+@itemx --count
+Prints only a count of messages in the mailbox and exit.
+
+@item -d
+@itemx --debug
+Prints additional debugging outut.
+
+@item -s @var{string}
+@itemx --sender=@var{string}
+Prints only mail from addresses containing the supplied string.
+FIXME: only @code{From:} header is examined.
+
+@item -f @var{url}
+@itemx --file=@var{url}
+Examine mailbox from the given @var{url}.
