# If you are working with many subroutines, there likely would happen some problems with run from line
# for safe workflow this filter can be used, you decide from where the file begins until END

# ini  [FILTER]
# PROGRAM_EXTENSION = .py Python Script

# py = python
# ngc = /home/path/to/folder/rfl_brave.py

# sudo chmod 755 /home/path/to/folder/rfl_brave.py and set executable.

# On first line of your .ngc file entry needed  #<_rfl> = 'line to start from', to use the .ngc file from this position to EOF.
# If first line is empty or #<_rfl> = 0 full file is run.
# Global named parameter #<_rfl> can be used for own purpose
# From this startpoint it is easy to start or run from line, avoiding any subroutines and get no trouble
