Kolejna propozycja rozwiazania problemu usuwania userow i grup, z
przykladami zastosowania.
Pierwsze dwa makra (%usertestrm/%grouptestrm) sa przeznaczone do obslugi
sytuacji niestandardowych, np gdy trzeba do userdel podac opcje "-r" lub
oprocz usuniecia usera zrobic cos jeszcze.
Ostatnie dwa makra sa pomyslane jako podstawowe.
Pozwolilem sobie umiescic obsluge zalosci w jednym skrypcie, bo chyba
wydajnosc nie jest tu szczegolnie istotna.
Poziom "rozmownosci", przy ktorym sa wypisywane odp. komunikaty zostal
oczywiscie wziety z sufitu.
Uwagi? Komentarze?
Jutro mnie nie ma, ale w niedziele/poniedzialek moge sie wziac za wdrazanie
tej implementacji...
