# 1. Recursively search through all go files for any lines that include a direct import from go-ethereum
# 2. Ignore lines that import geth with a named import starting with "eth" or by _ import.
# 3. Sort the unique results.
# 4. Print out the difference between the search results and the list of specified allowed package imports from geth.
