| Subject: | Wishlist: Ability to stipulate alternative compression engine |
Presently, it appears the choice of compression engine is limited to that provided by stock Tar.
And then, which tar compression engine is used is based on the file extension.
This limits choices in the event somebody wants to use something like Googles Zopfli compressor, which can get as much as 6% advantage over Zlib while still emitting a Gzip decodable .gz file.
In the event support is added for things like Zopfli, it is worth noting that Zopfli itself takes a parameter in the form:
--iN
Where "N" is a number indicating a number of rounds to perform ( which is basically a time trade-off for progressively decreasing returns )
