6 # certain source tree changes, including:
7 # - removing source files
8 # - replacing generated files with files committed to the tree
9 # - changing file extensions (e.g. a C source file rewritten in C++)

12 # bad case in the main .depend file, and if found deleting all of the related
13 # .depend files (including for example the lib32 version).
