#======================================================================

# HISTORY:

#	May 15, 2013: - created from [LWplot_prof]

#	Oct 30, 2103: - got rid of non-portable echo -e

#	Nov  3, 2014: - adapted to updated layout of .prof file

#	Apr  5, 2015: - made fixbb optional

# NOTES:

#	- this version plots 2-beam solutions instead of final w
