2858 # will use it. (This is not the normal case.)
2860 # Otherwise need to regenerate .pc so that dpkg-source --commit
2861 # can work. We do this as follows:
2862 # 1. Collect all relevant .orig from parent directory
2863 # 2. Generate a debian.tar.gz out of

2866 # Format Source Version Files
2867 # 4. Extract the fake .dsc
2868 # Now the fake .dsc has a .pc directory.
2869 # (In fact we do this in every case, because in future we will
2870 # want to search for a good base commit for generating patches.)
2872 # Then we can actually do the dpkg-source --commit
2873 # 1. Make a new working tree with the same object
2874 # store as our main tree and check out the main
2876 # 2. Copy .pc from the fake's extraction, if necessary
2877 # 3. Run dpkg-source --commit
2878 # 4. If the result has changes to debian/, then
2879 # - git-add them them
2880 # - git-add .pc if we had a .pc in-tree
2882 # 5. If we had a .pc in-tree, delete it, and git-commit
2883 # 6. Back in the main tree, fast forward to the new HEAD
2885 # Another situation we may have to cope with is gbp-style
2886 # patches-unapplied trees. We want to detect these, so we know
2887 # to escape into quilt_fixup_gbp.
2889 # A gbp-style tree is one which is not a clean patches-applied
2890 # tree, but _is_ a clean patches-unapplied tree.
2892 # To help detect this, when we are extracting the fake dsc, we

2894 # afterwards with dpkg-source --before-build. That lets us save a
