gstats [selection options] files
Gstats is a shell script based on gpr. It uses the facilities provided by gpr to choose an output format for the summary data and histogram.
Because gstats is a shell script, its error output may sometimes be misleading.
Gstats is very similar to the old version. There are some major differences in behaviour, but these are due to changes in gpr.
