#

# Vendor-specific MIME type <-> extension mappings

#

# Each line below defines a mapping from one MIME type to the first of the

# listed extensions, and from listed extension back to the MIME type.

#

# This file can _add_ additional mappings that are not in the default set,

# but it it cannot _modify_ (replace or remove) any platform default mapping

# (defined in files mime.types and android.mime.types).

#

###############################################################################

#

# EXAMPLES

#

# A line of the form (without the leading '#''):

#

#    mime ext1 ext2 ext3

#

# affects the current mappings along the lines of the following pseudo code:

#

#    mimeToExt.putIfAbsent("mime", "ext1");

#    extToMime.putIfAbsent("ext1", "mime");

#    extToMime.putIfAbsent("ext2", "mime");

#    extToMime.putIfAbsent("ext3", "mime");

#

# Optionally, MIME types or extensions may be prefixed by a single '?', which

# will be ignored. I.e., the following example lines all have the same semantics:

#

#    mime ext1 ext2 ext3

#    ?mime ext1 ext2 ext3

#    mime ?ext1 ext2 ?ext3

#    ?mime ?ext1 ?ext2 ?ext3

#

# By default, this file contains no mappings (which means that the platform

# default mapping is used unmodified).

#

###############################################################################

#

# Add your custom mappings below this line (with no "#" at the start of the line):
