lrztar GNU/bash wrapper script for lrzip and tar input/output over directories.

Usage : lrztar [lrzip options] <directory>
Result: a lrzip tarball is produced.
Extras: when an lrzip tarball is used with -d, -O, it gets extracted:
-h: will display this message.
-d: <path1> will decompress a <path1> lrzip tarball to current directory.
-O: <path2> will decompress a -d specified lrzip tarball to <path2> path.
-f: will force overwrites.
Notice:
- The input argument is always last, all options and their arguments precede.
- The -O flag is an option flag, goes before: (-O <somedir> <input arg>).
- You can use the remaining options of lrzip as they were.
- lrzuntar is equivalent to lrztar [options] -d <filename>.
- This script exists because of how lrzip behaves.
- Beware the -f flag, it stands for what it says...
