#Edit script for btt bathymetry data to remove data lines which
#contain no position data.  This is evidenced by the appearance
#of 999999's in the line and/or by the appearance of 00000000's
#in the line.  Edited file retains the same name as the
#original filename and the original data is saved in a file 
#called original-name.1 (i.e. a .1 is appended to the name)

# Restrition.  Input parameter must be a single filename, with
# no wild card characters.

# Assumes output to current directory
