Denis Knauf 3cc205cb02 ruby-2.5-support fix. usage with rest-arguments. ... ruby-2.5 does not support `String#split() {|t|}`. splits are replaced by `String#split().each {|t|}`. Usage supports printing rest-arguments. It uses the name with three dots: command [<argname> ...] Sub-commands has a generic `<command> ...` or `[<command> ...]`. The last will be used if a nil-aliases exists.		2021-12-08 23:52:05 +01:00
