; NAME:
;  mpc_getline_orbits
;
; PURPOSE: (one line)
;  Return the raw catalog line from the MPC for a given ID
;
; DESCRIPTION:
;  Return the raw catalog line from MPC for a given ID or IDs.
;  The catalog line is a single line of text which is human-readable,
;  although it must be carefully interpreted.
;
; This routine searches through the catalog using grep.  For small
; catalogs like this, grep is fast enough.
; 
;
; CATEGORY:
;  MPC
;  
; CALLING SEQUENCE:
;  lines = oc_getline_mpc( ids [, NSTARS=nstars] [, /VERBOSE])
;
; INPUTS:
;  IDs -- A list of ID's.  Scalar or vector.
;   IDs must be one of the following formats 
;  * provisional designation, such as "2003 EL61"
;  * packed provisional designation, such as "K03E61L"
;  * number, such as 2060L (should be long)
;  * name, such as Chiron
;  * line number in the file, such as 1
;
; OPTIONAL INPUT PARAMETERS:
;  None
;  
; KEYWORD INPUT PARAMETERS:
;  /provisional
;  /packed_provisional
;  /number
;  /name
;  /line
;  filename = filename to search (needed for /line)
;  /VERBOSE -- If set, print diagnostics to screen.
;
; KEYWORD OUTPUT PARAMETERS:
;  NSTARS -- Returns the number of successfully-retrieved lines.
;
; OUTPUTS:
;  If input is a scalar, then output is a single string.
;  If input is a vector, then output is an array of strings.
;  If a star is not found, returned value is ''.
;  
; COMMON BLOCKS:
;  None
;
; SIDE EFFECTS:
;  None
;
; RESTRICTIONS:
;  MPC catalogs must be available at $WCS_CATDIR/sao/catalog.dat .
;
; EXAMPLE:
;  print, oc_getline_sao(['430', '1000'])

; MODIFICATION HISTORY:
;  Written  -Nov-2005 by Henry Throop, SwRI
;  Modified 27-Feb-2006 by HBT. Improved documentation and formatting.
;  Modified 05-Mar-2006 by LAY. Change nstars to count (consistent
;                               with oc_getline_ucac2)
;  Modified 15-Mar-2006 by HBT. Undid LAY's nstars change (hah!), 
;                               as it already was consistent w/ ucac2.
;  Modified 10-Nov-2006 by LAY. Close opened lun.
