NAME
  dp - parse dates RFC 822-style

SYNOPSIS
  /usr/lib/mh/dp [ -form file ] [ -format string ] [ -help ] [ -width columns
  ] dates

DESCRIPTION
  The dp command parses dates according to the ARPA Internet standard.	It
  also understands many non-standard formats, such as those produced by
  TOPS-20 sites and some UNIX sites using ctime(3). It is useful for seeing
  how MH will interpret a date.

  The dp program treats each argument as a single date, and prints the date
  out in the official RFC 822 format.  Hence, it is usually best to enclose
  each argument in double quotes (") for the shell.

FLAGS
  -form file
	    Overrides the default output format of dp.	The output is
	    formatted according to the instructions in the specified file.
	    This must be a format file; see mh-format(4).

  -format string
	    Overrides the default output format of dp.	The output is
	    formatted according to the instructions in the specified string.
	    This must be a format string; see mh-format(4).

	    The argument to the -format option must be interpreted as a
	    single token by the shell that invokes dp.	Therefore, you should
	    usually place the argument to this option inside double quotes
	    (").

  -help	    Prints a list of the valid options to this command.

  -width columns
	    Specifies the width of the screen in columns.

  The defaults for this command are as follows:

       -width defaults to the width of the terminal

EXAMPLES
  This is the default format string used by dp:

       %<(nodate{text})error: %{text}%|%(pretty{text})%>

  When an error is detected, this prints error: and the date that is in
  error. Otherwise, it outputs the proper RFC 822 format of the date.
