@ -23,7 +23,24 @@ For your own programs, simply create an AppImage-style AppDir and run `appdwarf
You can also invoke `appdwarf -a {appimage}` to convert an apimage.
I suggest checking the help (listed via `appdwarf --help`) for other options.
The apps folder contains other scripts for specific programs that will download all necessary files and create a resulting appdwarf in the same folder.

## `zzexe`
`zzexe` is a small tool similar to `gzexe` that instead uses zstd to compress single applications.
I've included it because it has a similar goal to `appdwarf` on the whole, just on a smaller scale.
I wrote it in part because I felt that `gzexe` was overly complicated, as I used to
just use a lightly modified version of it that replaces `gzip` with `zstd`,
and to add a couple additional features.
It supports adding in a prefix command to the file using the `-p` options e.g.
`zzexe -p wine some.exe` will generate a compressed file that will then run the exe.
It also automatically appends the extension of the source file to the temporary file
created when ran since some programs care about that, such as an emulator only
running games of an expected file extension.
