2373 # We first look for a .pc in the git tree. If there is one, we
2374 # will use it. (This is not the normal case.)
2376 # Otherwise need to regenerate .pc so that dpkg-source --commit
2377 # can work. We do this as follows:
2378 # 1. Collect all relevant .orig from parent directory
2379 # 2. Generate a debian.tar.gz out of
2380 # debian/{patches,rules,source/format}

2382 # Format Source Version Files
2383 # 4. Extract the fake .dsc
2384 # Now the fake .dsc has a .pc directory.
2385 # (In fact we do this in every case, because in future we will
2386 # want to search for a good base commit for generating patches.)

2389 # 1. Make a new working tree with the same object
2390 # store as our main tree and check out the main
2392 # 2. Copy .pc from the fake's extraction, if necessary
2393 # 3. Run dpkg-source --commit
2394 # 4. If the result has changes to debian/, then
2395 # - git-add them them
2396 # - git-add .pc if we had a .pc in-tree
2398 # 5. If we had a .pc in-tree, delete it, and git-commit
