Version 21 of psmisc is now uploaded and ready for you to play with. In this version the signames problem (where some builds would have a problem when you try -USR1 and you sent SIGPWR instead) has been fixed, I hope. If you have problems please let me know.
This version also has locales so it should talk to you in your language. A BIG thanks to the translators for their efforts. If you want psmisc to speak your language and want to help out with the translations let me know.
