| 7 # XXX To do: | |
| 8 # - accept filename arguments | |
| 9 # - turn trailing C comments into Python comments | |
| 10 # - turn C string quotes into Python comments | |
| 11 # - turn C Boolean operators "&& || !" into Python "and or not" | |
| 12 # - what to do about #if(def)? | |
| 13 # - what to do about macros with parameters? | |
| 14 # - reject definitions with semicolons in them | |
