 The +conflate+ command conflates two maps into a single map.  If the specified output file name ends with the extension .osc, an OSM
 changeset will be written, instead of an OSM map.
 
-* +input1+         - First input; may be any supported input format (e.g. OSM file).
-* +input2+         - Second input; may be any supported input format (e.g. OSM file, XML changeset file (.osc)).
-* +output+         - The output path; may be any supported output format
-* +--differential+ - Calculates the the differential between two conflation inputs.  The output will be all elements in input2 that do
-                     not conflict with any elements in input1.
-* +--include-tags+ - Include a check for modified tags when doing differential conflation.  The output will include unmodified geometries
-                     from Input1, with new/updated tags from Input2 applied, using an overwrite-merge.
-* +--stats+        - Hootenanny map statistics such as node and way count; must be the last option entered and may be optionally followed
-                     by an output JSON file name
