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 automat-
       ically 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  hexa-
       decimal 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 alphanumeri-
       cally 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.
