https://www.gnipsel.com/fengrave/fengrave01.html works!!. I faced the following issues:
Running ./fengrave for the first time, I got this error:
kaustubh@Workbench:/opt/fengrave$ ./fengrave
Traceback (most recent call last):
File "./fengrave", line 297, in <module>
from Tkinter import *
File "/usr/lib/python2.7/lib-tk/Tkinter.py", line 42, in <module>
raise ImportError, str(msg) + ', please install the python-tk package'
ImportError: No module named _tkinter, please install the python-tk package
Resolved by running sudo apt install python-tk
