USAGE: $MYNAME COMMAND [PARAMS...]

COMMAND:
 catalog                       Fetch the catalog file from $ftpuri
 query MODEL [MODEL ...]       Get a list of packages for system model(s)
 get PACKAGE [PACKAGE ...]     Get the package(s) from ftp.dell.com
 id PACKAGE [PACKAGE ...]      Print component ID(s)
 pull MODEL                    Get all packages for the system model

This tool requires access to "$ftpsource". Check firewall and proxy settings
for proper access. 

Define environment variable "DROUTPUTDIR" to direct where to put downloaded
files. The default is current directory. For example:
$ DROUTPUTDIR=/publicnfs $MYNAME pull R610
