###############################################################################
#
# Android-specific MIME type <-> extension mappings
#
# Each line below defines an mapping from one MIME type to the first of the
# listed extensions, and from listed extension back to the MIME type.
# A mapping overrides any previous mapping _from_ that same MIME type or
# extension (put() semantics), unless that MIME type / extension is prefixed with '?'
# (putIfAbsent() semantics).
#
#
###############################################################################
#
# EXAMPLES
#
# A line of the form:
#
# ?mime ext1 ?ext2 ext3
#
# affects the current mappings along the lines of the following pseudo code:
#
# mimeToExt.putIfAbsent("mime", "ext1");
# extToMime.put("ext1", "mime");
# extToMime.putIfAbsent("ext2", "mime");
# extToMime.put("ext3", "mime");
#
# The line:
#
# ?text/plain txt
#
# leaves any earlier mapping for "text/plain" untouched, or maps that MIME type
# to the file extension ".txt" if there is no earlier mapping. The line also
# sets the mapping from file extension ".txt" to be the MIME type "text/plain",
# regardless of whether a previous mapping existed.
#
###############################################################################
# File extensions that Android wants to override to point to the given MIME type.
#
# After processing a line of the form:
# ?<mimeType> <extension1> <extension2>
# If <mimeType> was not already mapped to an extension then it will be
# mapped to <extension1>.
# <extension1> and <extension2> are mapped (or remapped) to <mimeType>.
