Could you clarify the difference with GZip.jl on the readme?

[fonsp]

They are both owned by JuliaIO, both (de)compress gzip, and both are up-to-date?

[ViralBShah]

Would be nice to update the README of both packages on when to use which.

Is GZip.jl still being maintained? Also, should we recommend using CodecZlib.jl or Inflate.jl on GZip.jl's README?

[ViralBShah]

Yes we should recommend alternatives.

[nhz2]

Looking at GZip.jl again, its gzopen function has some options that are difficult to recreate with CodecZlib.jl. For example, auto switching between compression and decompression based on if the file is opened in "r" or "w" modes, an "x" mode to create the file exclusively, and the "f", "h", "R", and "F" compression strategy options.

JuliaIO/GZip.jl#120

[nhz2]

#109 adds support for the "f", "h", "R", and "F" compression strategy options.
"x" mode to create the file exclusively is out of scope for this package because it will be OS dependent.
