Scripts to extract data from MOPAC calculations?

Question

I am doing calculations with MOPAC semi-empirical package.

As I have many systems (around 40), extracting the date manually, besides being tiring it can cause errors.

I already worked with ASE, but the data it can extract is very limited.

My question is: Are there available scripts (Bach, Python, etc.) to automatically extract data from MOPAC calculations?

Note: I am thinking in extracting all (or most all) the useful data: heat of formation, molecular orbitals (w/, w/o spin polarization), energies, frequencies, thermochemistry data, forces, etc.

I created the script bellow to extract the data I'm interested in from all MOPAC out files put inside a given folder and create a CSV file with all the data:

#!/bin/sh
#script to extract information from the output MOPAC file
#Use:
# ./fromMOPAC.sh folder_name
#
#The folder_name is a folder where all the MOPAC output files (.out) are located. A file with the name of the folder will be created with the data.
#
#

for filename in $1/*.out
do
