  -bi <blob-ids-file> | --strip-blobs-with-ids <blob-ids-file>
        strip blobs with the specified Git object ids
  -D <glob> | --delete-files <glob>
        delete files with the specified names (eg '*.class', '*.{txt,log}' - matches on file name, not path within repo)

  -rt <expressions-file> | --replace-text <expressions-file>
        filter content of files, replacing matched text. Match expressions should be listed in the file, one expression per line - by default, each expression is treated as a literal, but 'regex:' & 'glob:' prefixes are supported, with '==>' to specify a replacement string other than the default of '***REMOVED***'.
  -fi <glob> | --filter-content-including <glob>
        do file-content filtering on files that match the specified expression (eg '*.{txt,properties}')
  -fe <glob> | --filter-content-excluding <glob>
        don't do file-content filtering on files that match the specified expression (eg '*.{xml,pdf}')
  -fs <size> | --filter-content-size-threshold <size>
        only do file-content filtering on files smaller than <size> (default is 1048576 bytes)
  -p <refs> | --protect-blobs-from <refs>
        protect blobs that appear in the most recent versions of the specified refs (default is 'HEAD')
  --no-blob-protection
        allow the BFG to modify even your *latest* commit. Not recommended: you should have already ensured your latest commit is clean.
  --private
        treat this repo-rewrite as removing private data (for example: omit old commit ids from commit messages)
  --massive-non-file-objects-sized-up-to <size>
        increase memory usage to handle over-size Commits, Tags, and Trees that are up to X in size (eg '10M')
