`-h`

`-I`
  Ignore case in file name comparisons This option is slow for archives with many files.
`-i`
  Ask before overwriting files. See also `-s`.
`-k`
  Do not compress files that were uncompressed in source-zip, otherwise they are compressed with the default compression method.
`-S`
  Do not overwrite files that have the same size and CRC32 in both the source and target archives.
`-s`
  When `-i` is given, do not ask before overwriting files that have the same size and CRC32.
`-V`

# CAVEATS

`zipmerge` uses one open file descriptor per zip archive. If you need to merge a lot of zip archives, check your shell's file descriptor ulimit and either increase it or run `zipmerge` multiple times with e.g. 1000 source zip archives each time.
