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.
