GETDATA finds the data from start_time to end_time of type type for spacecraft voyager sc and writes them to its stdout. If dirs are given, then the data are looked for in those directories, else it looks for the data in the standard places. ( $vgrDATA/v${sc}/${type} ) (it does know that the EDRs are divided by quicklook/final and by years). GETDATA also can distinguish between compressed, zipped and plain files. Times are expressed in the form of yyddd[.hh]. sc is just the number of the spacecraft. GETDATA may call itself recursively if many files are needed. The actual writing of the data is done by GGG
