The tools in this package have different names, so they can be installed in
together with the existing tools:
- `gensquashfs` can be used to produce SquashFS images from `gen_init_cpio`
like file listings or simply pack an input directory.
- `rdsquashfs` can be used to inspect and unpack SquashFS images.
+ - `sqfs2tar` can turn a SquashFS image into a tar ball, written to stdout.
+ - `tar2sqfs` can turn a tar ball (read from stdin) into a SquashFS image.
Limitations

+ - no sparse files or hard links (converted to symlink)
