Synopsis:
    SNMP SMI/MIB files copying tool. When given MIB file(s) or directory(ies)
    on input and a destination directory, the tool parses MIBs to figure out
    their canonical MIB module name and the latest revision date, then
    copies MIB module on input into the destination directory under its
    MIB module name *if* there is no such file already or its revision date
    is older.
