+ # To do this we:
+
+ # Our git tree doesn't necessarily contain .pc. (Some versions of
+ # dgit would include the .pc in the git tree.) If there isn't
+ # one, we need to generate one by unpacking the patches that we
+ # have.
+ #
+ # We first look for a .pc in the git tree. If there is one, we
+ # will use it. (This is not the normal case.)
+ #
+ # Otherwise need to regenerate .pc so that dpkg-source --commit
+ # can work. We do this as follows:
+ # 1. Collect all relevant .orig from parent directory
+ # 2. Generate a debian.tar.gz out of
+ # debian/{patches,rules,source/format}
+ # 3. Generate a fake .dsc containing just these fields:
+ # Format Source Version Files
+ # 4. Extract the fake .dsc
+ # Now the fake .dsc has a .pc directory.
+ # (In fact we do this in every case, because in future we will
+ # want to search for a good base commit for generating patches.)
+ #
+ # Then we can actually do the dpkg-source --commit
+ # 1. Make a new working tree with the same object
+ # store as our main tree and check out the main
+ # tree's HEAD.
+ # 2. Copy .pc from the fake's extraction, if necessary
+ # 3. Run dpkg-source --commit
+ # 4. If the result has changes to debian/, then
+ # - git-add them them
+ # - git-add .pc if we had a .pc in-tree
+ # - git-commit
+ # 5. If we had a .pc in-tree, delete it, and git-commit
+ # 6. Back in the main tree, fast forward to the new HEAD
