This is from memory:


-R filename
	read timestamp file, Ie:  %d.%d second and fraction.

-r filename
	read phase difference file, Ie: .%d fraction

(I may have these two swapped)

-c
	Remove average

-l
	Make linear regression fit.

-A filename
	Calculate modified Allan variance

-a filename
	Calculate Allan variance

-F filename number_buckets
	FFT

-L number
	attemt Linear Frequency Fit with <number> points

-o omega
	time between samples.  (Should be given before [-rR])

-O stddev
	Remove Outlyers further than <stddev>.
