NAME

       mime.types - mime type description file for cups

DESCRIPTION

       The mime.types file defines the recognized file types.

       Additional file types are specified in files with the extension .types in the CUPS configuration directory.

       Each  line  in the mime.types file is a comment, blank, or rule line.  Comment lines start with the # character.  Rule lines start with the
       MIME media type and are optionally followed by a series of file recognition rules:

	   mime/type [ rule ... rule ]

       Rules can be extended over multiple lines using the backslash character ():

	   mime/type [ really-really-really-long-rule ... 
	     rule ]

       MIME media types specified by the mime/type field are case-insensitive and are sorted in ascending alphanumeric order for the  purposes	of
       matching.  See the "TYPE MATCHING AND PRIORITY" section for more information.

       The  rules  may	be  grouped  using  parenthesis,  joined using "+" for a logical AND, joined using "," or whitespace for a logical OR, and
       negated using "!".

   RULES
       Rules take two forms - a filename extension by itself and functions with test values  inside  parenthesis.   The  following  functions  are
       available:

       match("pattern")
	    True if the filename matches the given shell wildcard pattern.

       ascii(offset,length)
	    True if the length bytes starting at offset are valid printable ASCII (CR, NL, TAB, BS, 32-126).

       printable(offset,length)
	    True if the length bytes starting at offset are printable 8-bit chars (CR, NL, TAB, BS, 32-126, 128-254).

       priority(number)
	    Specifies  the  relative  priority	of  this  MIME media type.  The default priority is 100.  Larger values have higher priority while
	    smaller values have lower priority.

       string(offset,"string")
	    True if the bytes starting at offset are identical to string.

       istring(offset,"string")
	    True if the bytes starting at offset match string without respect to case.

       char(offset,value)
	    True if the byte at offset is identical to value.

       short(offset,value)
	    True if the 16-bit big-endian integer at offset is identical to value.

       int(offset,value)
	    True if the 32-bit big-endian integer at offset is identical to value.

       locale("string")
	    True if current locale matches string.

       contains(offset,range,"string")
	    True if the bytes starting at offset for range bytes contains string.

   STRING CONSTANTS
       String constants can be specified inside quotes ("") for strings containing whitespace and angle brackets (<>) for hexadecimal strings.

   TYPE MATCHING AND PRIORITY
       When CUPS needs to determine the MIME media type of a given file, it checks every MIME media type defined in the .types files.  When two or
       more types match a given file, the type chosen will depend on the type name and priority, with higher-priority types being used over lower-
       priority ones.  If the types have the same priority, the type names are sorted alphanumerically in ascending order and the  first  type	is
       chosen.

       For  example, if two types "text/bar" and "text/foo" are defined as matching the extension "doc", normally the type "text/bar" will be cho-
       sen since its name is alphanumerically smaller than "text/foo".	However, if "text/foo" also defines a  higher  priority  than  "text/bar",
       "text/foo" will be chosen instead.

FILES

       /etc/cups - Typical CUPS configuration directory.

EXAMPLES

       Define two MIME media types for raster data, with one being a subset with higher priority:

	   application/vnd.cups-raster	string(0,"RaSt") string(0,"tSaR") 
					 string(0,"RaS2") string(0,"2SaR") 
					 string(0,"RaS3") string(0,"3SaR")

	   image/pwg-raster		 string(0,"RaS2") + 
					 string(4,PwgRaster<00>) priority(150)
