8 | # This script checks for duplicate includes. It also has support | |
9 | # to remove them in place. Note that this will not take into | |
10 | # consideration macros so you should run this only if you know | |
11 | # you do have real dups and do not have them under #ifdef's. You | |
12 | # could also just review the results. | |
