2.1.2 Command-line Options
  The reference section describes all command line switches and INI file keywords that are used to set the options of 
 POV-Ray. It is supposed to be used as a reference for looking up things. It does not contain detailed explanations on 
 how scenes are written or how POV-Ray is used. It just explains all features, their syntax, applications, limits, 
 drawbacks, etc. 
 
  Options may be specified by switches or INI-style options. Almost all INI-style options have equivalent  +/ 
 - switches and most switches have equivalent INI-style option. The following sections give a detailed 
 description of each POV-Ray option. It includes both the INI-style settings and the  +/ - 
 switches. 
 
  The notation and terminology used is described in the tables below. 
 
 
 
  
  
    Keyword=bool 
   | 
  
    Turn Keyword on if bool equals true,  yes, on or 1 
   and Turn it off if it is any other value. 
   | 
  
 
  
  
    Keyword=true 
   | 
  
    Do this option if true, yes,  on or 1 is specified. 
   | 
  
 
  
  
    Keyword=false 
   | 
  
    Do this option if false, no,  off or 0 is specified. 
   | 
  
 
  
  
    Keyword=filename 
   | 
  
    Set Keyword to filename where filename is any valid file name. 
   
     Note: some options prohibit the use of any of the above  true or false 
    values as a file name. They are noted in later sections. 
    | 
  
 
  
  | 
    n 
   | 
  
    Any integer such as in +W320 
   | 
  
 
  
  | 
    n.n 
   | 
  
    Any float such as in Clock=3.45 
   | 
  
 
  
  | 
    0.n 
   | 
  
    Any float < 1.0 even if it has no leading 0 
   | 
  
 
  
  | 
    s 
   | 
  
    Any string of text 
   | 
  
 
  
  | 
    x or y 
   | 
  
    Any single character 
   | 
  
 
  
  | 
    path 
   | 
  
    Any directory name, drive optional, no final path separator ("\" or "/", depending on the 
   operating system) 
   | 
  
 
  Unless otherwise specifically noted, you may assume that either a plus or minus sign before a switch will produce 
 the same results.
