+-- 1: Split `params_text` into two vars with unpack(wea.split(params_text,"%sdo%s"))
+-- 2: Further split the two vars into two tables, one of values and the other of {command, args} sub tables
+-- 3: For each entry in the values table execute each {command, args} sub table using gsub to replace "%%" in the args with the current value

+-- Specs:
+-- Command cluster support using ()
+-- ?Basename support for values
+-- ?Comma deliniation support for values
