Utility maintaining the INF.SYS file. The INF.SYS file holds the users'
database. In case of problem in INF.SYS file, goto the SYSTEM directory and
run MAINTINF followed by a number of months. The records of  users not
connected within this number of months will be deleted and these users will
be asked as for a new connection. The number 0 will not delete any record and
only check the INF.SYS file.
