## 8/12/24
- Removed `on_shutdown` function from `src/main.rs`, as it was uselessly dropping memory that was automatically dropped right after the function ended.
- Finished the documentation for `src/main.rs`, `src/packages/installed.rs`, `src/packages/browse.rs`, and `src/packages/mod.rs`
- Renamed `show_installed_package` to `show_package`, and merged it into `src/packages/mod.rs` instead of having copies in two files.
- Added this changelog.
- Updated `inst.sh` so that it no longer copies `style.css` to the `/usr/share/oreon-system-manager` directory.
