# Mapcss-mapping format
#
# A CSV table mapping tags to types. Some types can be deemed obsolete, either completely or replaced with a different type.
#
# Example row: highway|bus_stop;[highway=bus_stop];;name;int_name;22; (mind the last semicolon!)
# It contains:
# - type name: "highway|bus_stop" ('|' is converted to '-' internally)
# - mapcss selector for tags: "[highway=bus_stop]" (you can group selectors and use e.g. [oneway?])
# - "x" for an obsolete type or an empty cell otherwise
# - primary title tag (usually "name")
# - secondary title tag (usually "int_name")
# - type id, sequential starting from 1
# - replacement type for an obsolete tag, if exists
#
# A shorter format for above example: highway|bus_stop;22;
# It leaves only columns 1, 6 and 7. For obsolete types with no replacement put "x" into the last column.
# Obviously it works only for simple types that are produced from tags replacing '=' with '|'.
#
# An example of type with replacement:
# highway|unsurfaced|disused;[highway=unsurfaced][disused?];x;name;int_name;838;highway|unclassified
# The mapcss-mapping.csv format is described inside the file itself.
