Shows output from shell as script runs.
kext permissions: sets permissions to all files in your extensions folder.
make script: makes a install script for the chosen kexts.
tag cache rebuild: makes script for touch extensions folder, so cache gets rebuild on next boot.
Run ->: runs the current script, so be sure you got no errors if you edited it.
When you already have a file with the name you are installing, the old one will be put in a folder name "Backup Extensions" on the root of your system disk.
Doesn't support files with spaces in the file name (spaces in the path to the file works fine).
Use at your own risk. I hope you find it useful.
