Is any reason, why still use mipcore and genpuid v1.3 ? v1.4 has some speed improvements ( but no 100% ) and maybe usefull switeches

-r                     Process directories recursively
-threads=#       Use multiple threads during processing

Hi genpuid 1.4 only came out on November 26th. After testing Jaikoz will be updated to Genpuid 1.4
