There were some modules that did not offer "or (at your option) any later version" in their license and these had to be left alone. This should solve the incorrect FSF address issue #4 on GitHub.

|
|
# foo

# ===

# It ignores the amount of whitespace after the title and the
|
|
# underlining, and it allows underlining using ==== or ----. The

|
# underlining has to be exactly as wide as the title itself. If it is
