I have a number of backed up ISO files that were taking up quite a bit of space. I wanted to save some space and I decided to compress them. Instead of putting them into something like a ZIP archive, I decided that compressing into CSO would be the most usable option.
Sadly, there is a lack of CSO compression and decompression tools that can
be easily installed using something like homebrew. Thus,
cstools is a Python project I wrote which can run as a command line
application. To make it even more useful, the package is also a Python module
that other Python applications can import. It provides CSO compression and
The project also includes a
pyproject.toml file to allow packaging and installation
pip. It can be found here.
