# Script
#     foamProbe
#
# Description
#     Proccess a scalar, vetorial or tensorial field of OpenFOAM 
#     probe file (for monitoring points). The original file will not be changed
#     and the fields of each monitoring point will be stored in a new
#      directory named probe<Name> (where <Name> is the field name) in the
#     directory where are the original probes files.
#     The fourth optional parameter can be used to create xmgrace sequentially
#     graphs (case is 0)  
#     for monitoring points or automatically create eps figures (case is 1).
