# we are storing 'everyone' to begin a thought.  we are storing it permanently

# we want to encrypt filename too, for what-I-call respect,
# so let's put each file in its own tarball, preferably in subdir,
# and add each filename to an index that is also uploaded, for ease finding.
# we can write down the filenames locally too.  but is sufficient to write down
# the index. =)

# REMAINING:
# 0. store download-script in repo, and on blockchain

# 1. store download-script url on USB key
# 1b. store details on backup USB key too.
# 3. try to download without usb key, as test for failure
# 4. move btc from community or from git-remote-bsv to repo bsvup
# 5. upload the encrypted repo
# 6. download the encrypted repo, as a test
# 9. consider storing bsvup transaction details in git history, to reuse transaction information.
