The feature of golang having source in a project path with "internal" makes the code only able to be imported by the project itself. https://docs.google.com/document/d/1e8kOo3r51b2BWtTs_1uADIA5djfXhPT36s6eHVRIvaU/edit?tab=t.0 Since we have this carried version of `archive/tar` with our byte accounting patches, it is also means the version of archive/tar has not kept up with upstream. our tar-split libraries do not even utilize all the function calls of our carried archive/tar, so might as well limit anyone else in the world from calling them as well.

tar-split utility
Installation
go get -u github.com/vbatts/tar-split/cmd/tar-split
Usage
Disassembly
$ sha256sum archive.tar
d734a748db93ec873392470510b8a1c88929abd8fae2540dc43d5b26f7537868 archive.tar
$ mkdir ./x
$ tar-split disasm --output tar-data.json.gz ./archive.tar | tar -C ./x -x
time="2015-07-20T15:45:04-04:00" level=info msg="created tar-data.json.gz from ./archive.tar (read 204800 bytes)"
Assembly
$ tar-split asm --output new.tar --input ./tar-data.json.gz --path ./x/
INFO[0000] created new.tar from ./x/ and ./tar-data.json.gz (wrote 204800 bytes)
$ sha256sum new.tar
d734a748db93ec873392470510b8a1c88929abd8fae2540dc43d5b26f7537868 new.tar
Estimating metadata size
$ tar-split checksize ./archive.tar
inspecting "./archive.tar" (size 200k)
-- number of files: 28
-- size of metadata uncompressed: 28k
-- size of gzip compressed metadata: 1k
