2441 # will use it. (This is not the normal case.)

2447 # debian/{patches,rules,source/format}

2450 # 4. Extract the fake .dsc
2451 # Now the fake .dsc has a .pc directory.
2452 # (In fact we do this in every case, because in future we will
2453 # want to search for a good base commit for generating patches.)
2455 # Then we can actually do the dpkg-source --commit
2456 # 1. Make a new working tree with the same object
2457 # store as our main tree and check out the main
2459 # 2. Copy .pc from the fake's extraction, if necessary
2460 # 3. Run dpkg-source --commit
2461 # 4. If the result has changes to debian/, then

2463 # - git-add .pc if we had a .pc in-tree
