2371 # Our git tree doesn't necessarily contain .pc. (Some versions of

2376 # We first look for a .pc in the git tree. If there is one, we
2377 # will use it. (This is not the normal case.)
2379 # Otherwise need to regenerate .pc so that dpkg-source --commit
2380 # can work. We do this as follows:
2381 # 1. Collect all relevant .orig from parent directory
2382 # 2. Generate a debian.tar.gz out of
2383 # debian/{patches,rules,source/format}
2384 # 3. Generate a fake .dsc containing just these fields:
2385 # Format Source Version Files
2386 # 4. Extract the fake .dsc
2387 # Now the fake .dsc has a .pc directory.
2388 # (In fact we do this in every case, because in future we will
2389 # want to search for a good base commit for generating patches.)
2391 # Then we can actually do the dpkg-source --commit
2392 # 1. Make a new working tree with the same object
2393 # store as our main tree and check out the main
2395 # 2. Copy .pc from the fake's extraction, if necessary
2396 # 3. Run dpkg-source --commit
2397 # 4. If the result has changes to debian/, then
2398 # - git-add them them
2399 # - git-add .pc if we had a .pc in-tree
2401 # 5. If we had a .pc in-tree, delete it, and git-commit
