add_license_to_files.jl
#!/usr/bin/env julia
# This file is a part of Julia. License is MIT: https://julialang.org/license
# Adds the julia license line `new_license` to configured file extensions in `rootdirs`.
#
# Option `old_license` to remove an existing license first in case one wants to change the
# license text in the future.
#
# Checks also if somewhere else in the file the license text is found (`copy/past error`)
# and if possible deletes such lines - if other text is on the same line it raises an error.
