DESCRIPTION

       The mime.types file defines the recognized file types.

       Additional file types can be added to mime.types or in additional files
       in the configuration directory /etc/cups 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 recogni-
       tion rules that are used to automatically identify print and web files:

           super/type rule [ ... ruleN]
       The rules may be grouped using parenthesis, joined using "+" for a log-
       ical 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 avail-
       able:

       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)

       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
