    disk.

    Arguments:
        DATABASE  the database name. Currently supported database are:
                  1) "cdms":  the Cologne Database for Molecular Spectrocopy
                     (CDMS)
                  2) "voparis: the Paris VO  observatory  interface  to  the

    Options:
        /LOWER    minimum  line  frequency to be stored in the cache, in MHz
                  (default 0)

        /UPPER    maximum line frequency to be stored in the cache,  in  MHz
                  (default 2e6 MHz, i.e. 2 THz)

        /STEP     frequency  interval for each database query. If one obtain
                  a timeout error or a message saying that the database  re-
