I put this script quickly together so I could follow the call stack in the profiler data.

AddCallStackColumnToProfileDataFile

# textToTree 
# This script takes a tab delimited file in the form:
#  x.y.a ...
#   x.y.b ...
#    x.y.c ...
#  x.y.d ...
# 
#  And produces a file in the form:
#  x.y.a ... [y#a]
#   x.y.b ... [y#a, y#b]
#    x.y.c ... [y#a, y#b, y#c]
#  x.y.d ... [y#d]
# 
#  I put this script quickly together so I could add the call stack to profiler output data.
