This is as a follow up of WINDUP-1141 (ref. doc. link https://doc-stage.usersys.redhat.com/documentation/en/red-hat-jboss-migration-toolkit/3.0/single/windup-user-guide#command_line_arguments)

There were added:

The ruleset files must end in .windup.xml.

which sounds to me weird.

Shouldn't the correct explanation be like

The ruleset files must end with .windup.xml suffix ?
