+== validate
+
+=== Description
+
+The +validate+ command uses JOSM to identify (but does not fix) data with common erroneous aspects. This command is only available when
+Hootenanny is configured with JOSM (compiled --with-josm).
+
+* +input+                  - Input; may be any supported input format (e.g. .osm file).
+* +output+                 - (optional) Output file; may be any supported output format (e.g. .osm file). If specified, elements with 
+                             validation will be marked with tags in the output file. If not specified, then only a validation error summary 
+                             will be displayed.
+* +--available-validators+ - Displays available JOSM validators for use in validation. Not all validators have cleaning (auto-fix) capabilities. 
+                             If this option is selected, neither an input or output must be specified.
