2361 # We first look for a .pc in the git tree. If there is one, we
2362 # will use it. (This is not the normal case.)
2364 # Otherwise need to regenerate .pc so that dpkg-source --commit
2365 # can work. We do this as follows:
2366 # 1. Collect all relevant .orig from parent directory
2367 # 2. Generate a debian.tar.gz out of
2368 # debian/{patches,rules,source/format}

2370 # Format Source Version Files
2371 # 4. Extract the fake .dsc
2372 # Now the fake .dsc has a .pc directory.
2373 # (In fact we do this in every case, because in future we will
2374 # want to search for a good base commit for generating patches.)
2376 # Then we can actually do the dpkg-source --commit
2377 # 1. Make a new working tree with the same object
2378 # store as our main tree and check out the main
2380 # 2. Copy .pc from the fake's extraction, if necessary
2381 # 3. Run dpkg-source --commit
2382 # 4. If the result has changes to debian/, then
2383 # - git-add them them
2384 # - git-add .pc if we had a .pc in-tree
2386 # 5. If we had a .pc in-tree, delete it, and git-commit
