2360 # Our git tree doesn't necessarily contain .pc. (Some versions of

2365 # We first look for a .pc in the git tree. If there is one, we
2366 # will use it. (This is not the normal case.)
2368 # Otherwise need to regenerate .pc so that dpkg-source --commit
2369 # can work. We do this as follows:
2370 # 1. Collect all relevant .orig from parent directory
2371 # 2. Generate a debian.tar.gz out of
2372 # debian/{patches,rules,source/format}
2373 # 3. Generate a fake .dsc containing just these fields:
2374 # Format Source Version Files
2375 # 4. Extract the fake .dsc
2376 # Now the fake .dsc has a .pc directory.
2377 # (In fact we do this in every case, because in future we will
2378 # want to search for a good base commit for generating patches.)
2380 # Then we can actually do the dpkg-source --commit
2381 # 1. Make a new working tree with the same object
2382 # store as our main tree and check out the main
2384 # 2. Copy .pc from the fake's extraction, if necessary
2385 # 3. Run dpkg-source --commit
2386 # 4. If the result has changes to debian/, then
2387 # - git-add them them
2388 # - git-add .pc if we had a .pc in-tree
2390 # 5. If we had a .pc in-tree, delete it, and git-commit
