Thanks for the reminder a!!!
I was to upload the script somewhere and post the link here as the script and its related files were exceeding the forum limits but somehow I forgot

I've uploaded the script to GitHub and here is the download link,
pmpm-master.zip After downloading the archive, extract its contents into a directory, open that directory in your favorite terminal emulator and run the following commands,
chmod 755 install_pmpm
sudo ./install_pmpm
Remember to run the
install_pmpm using sudo. Running the
install_pmpm as the root is not allowed.
If your system has all the required dependencies then you'll get the "installation success" message, otherwise you will be warned about missing dependencies and the install process will be terminated. You'll have to re-run the install process after installing missing dependencies.
In my view
pmpm is easily one of the best tool out there for managing all the password related tasks plus it has many extra goodies you won't even find in other big programs. Give it a go and I'm sure you will like it.
Cheers!!!
