no it is not file -> export.

the file you downloaded has crap documentation - none. the link you provided says "There will be differences between the documentation here and the product in your hands, and you may have to figure out quite a bit for yourself." and that holds truth. you can open your pluginmanager and hit the [I] for information. it will tell you which commands the plugin provides. each of them opens a window to set options and export something. it is more trial and error than anything usable at first look at it.

good luck if you are dependant on this plugin
