c this routine requests the name of a specification file which
c contains input information for implementing the EMA flood
c frequency algorithm. The specification file is loosely based
c on the input file for USGS program PEAKFQ
c
c this was prepared by tim cohn, us geological survey, to support
c development of an operational version of peakfq (bulletin 17b
c implementation) which would include the expected moments
c algorithm (ema; cohn et al. 1997; 2001)

c Notes:
c 1) Observations are classified as "Systematic" iff the threshold
c corresponding to the observation does not exceed the gage-base
c discharge at the site.
c 2) Low-outlier identification is done using one of three options:
c "NONE"; "GBT" (Grubbs-Beck Test); "MGBT" (Multiple Grubbs-BeckTest)
c The option is stored in gbtype
