Command line flags not working

[GitGhillie]

Following the example from the readme I'm doing:
klafsa gltf --backend toktx --codec bc7 --container ktx2 Tower.gltf

But I'm getting:

error: Found argument '--backend' which wasn't expected, or isn't valid in this context

        If you tried to supply `--backend` as a value rather than a flag, use `-- --backend`

USAGE:
    klafsa.exe gltf [OPTIONS] <FILE_PATH>

For more information try --help

Any idea on what could be going wrong here?
Also, I noticed the last update was 2 years ago, so if this is not the recommended tool anymore please let me know!

Changing the order seems to do the trick:
klafsa --backend toktx --codec astc --container ktx2 gltf Tower.gltf

Now to figure out why none of the codecs seem to be working...

Edit: I'll continue to document my journey in case it is useful for documentation / spotting issues.

Looking at

klafsa/src/compressor.rs

Line 38 in f328d64

pub fn backend(&self) -> Option<Backend> {

it seems that each codec requires a specific backend, which makes me wonder why there is a --backend setting.
I've installed kram and am now hitting the following:

Edit: Got it working! I needed to specify the path: klafsa --backend kram --codec bc7 --container ktx2 gltf ./Tower.gltf
Let me know if I can help out with a PR to address some of the things I found.
