Program specified by user (currently hardcoded) will be invoked, the contents of the file being extracted supplied to its stdin, and its stdout saved instead of original file. It is something like `--to-command` from GNU tar I think it is way more universal than madler#4 which is kind of useless when you have more than one file in archive (and care about outputed filenames) Unfortunately prog's exit code is curently ignored - sunzip will keep running even if prog fail. This kinda suck, but it hugely simplifies integration with programs that panic on unrecognized input. TODO: - Add CLI (prog is curently hard-set to `tac` for testing purposes) - Improve child cleanup - Add option to enable exit code checking or at least inform on which files error occured - Add support for non-posix systems or at least make it optional feature (currently build on non-posix will probably fail)
