Normalise / compute mean, standard deviation

Normalise time series and/or compute mean, standard deviation

rms [-a -v -o outfile -l# -x# -c# -V# -h] file(s)

-a subtract average
-v subtract mean, normalise to unit variance
-l number of values to be read (all)
-x number of values to be skipped (0)
-c column to be read (1 or file,#)
-o output file name, just -o means file_a (if -a), file_v (if -v)
-V verbosity level (0 = only fatal errors)
-h show this message

Prints mean, standard deviation, minimal and maximal value of time series. Optionally subtracts mean and normalises to unit variance. Output file file_a (if -a is set) or file_v (if -v is set).
