NAME

       mime.types - mime type description file for cups

DESCRIPTION

       The mime.types file defines the recognized file types.

       Additional  file  types  can  be added to mime.types or (preferably) in
       additional files in the CUPS configuration directory with the extension
       ".types".

       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  type  name  and  are  optionally  followed  by  a  series of file
       recognition rules that are used to automatically identify print and web
       files:

           super/type rule [ ... ruleN]
       MIME  type  names  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 and "," 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")
            Pattern match on filename

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

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

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

       string(offset,"string")
            True if bytes are identical to string

       istring(offset,"string")
            True if a case-insensitive comparison of the bytes is identical

       char(offset,value)
            True if byte is identical

       short(offset,value)
            True if 16-bit integer is identical

       int(offset,value)
            True if 32-bit integer is identical

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

       contains(offset,range,"string")
            True if the range contains the 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 type of a given file,  it  checks
       every  MIME  type  defined in the .types files. When two types have the
       same matching rules, 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
       chosen  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.
