CONFIGFORMAT

 The configfile consists of lines in the following format 
configfile: | configfile T_NEWLINE configline ;
--
 one line can have the following contents: 
configline: /* nothing 
    load the given place file list 
   | T_PLACEFILE T_STRING {
--
    specify the start place by lattitude/longitude 
   | T_STARTPLACE lattitude longitude {
--
    specify origin (lattitude/longitude)
      of the coordinate system 
   | T_ORIGIN lattitude longitude {
--
    set the start place by a name of a place 
   | T_STARTPLACE T_STRING {
--
    width of the coordinate system in pixels 
   | T_FULLWIDTH T_NUM {
--
    height of the coordinate system in pixels 
   | T_FULLHEIGHT T_NUM {
--
    global xfactor 
   | T_XFACTOR realnum {
--
    global yfactor 
   | T_YFACTOR realnum {
--
    definition of a map 
   | T_MAP map 
--
    definition of a map 
map: T_STRING ' 
    or without a newline 
   | T_STRING ' 
--
    a map definition can consist of lines 
maplines: | maplines T_NEWLINE mapline
--
    in the following form 
mapline: /* nothing 
    a reference point with geographical coordinates
      and with x/y coordinates  relative to the origin specified above 
   | T_ORIGIN lattitude longitude T_NUM T_NUM {
--
    x scaling factor relative to the global coordinate system 
   | T_XFACTOR realnum {
--
    y scaling factor relative to the global coordinate system 
   | T_YFACTOR realnum {
--
    tile width (width of a single file) 
   | T_TILEWIDTH T_NUM {
--
    tile height (height of a single file) 
   | T_TILEHEIGHT T_NUM {
--
    file pattern: %X and %Y are replaced
      with the x and y number of the tile, 
      both must appear
      printf modifiers are allowed (0, - and 0-9) 
   | T_FILEPATTERN T_STRING {
--
 a longitude can be defined as
   a degree followed  by E for east 
longitude: degree 'E' 
 or by W for west 
	 | degree 'W' 
--
 a lattitude can be defined as
   a degree followed by N for north 
lattitude:  degree 'N' 
 or by S for south 
	 | degree 'S' 
--
 a degree can contain the degree with 
   minutes separated by the ° character
degree: realnum '°' degmin  
 or  minutes only 
        | degmin 
 or  seconds only 
	| degsec 
--
 minutes can be minutes with secods  
degmin:  realnum '\'' degsec 
 or only minutes followed by the ' character 
        | realnum '\'' 
--
 seconds followed by '' 
degsec: realnum '\'' '\''
