## About The Project
**πireal** is a teaching tool for use in learning introduction to database. It allows the user to interactively experiment with Relational Algebra.
### Built With
* [Python](https://python.org/)
* [PyQt](https://riverbankcomputing.com/software/pyqt/intro)
* [Qt](https://www.qt.io/)
## Getting Started
You can download the installer from [here](). Currently we only have installer for Windows and Debian. If you know how to pack for Mac OS or any other Linux distribution, I'll thank you.
There is always the option to execute from the sources:
### Prerequisites

```
$ make pip-install
```
Take a look the `Makefile` for more commands:
```
$ make
test -- run tests
test-gui -- run tests for GUI
test-integration -- run integration tests
pep8 -- run pycodestyle
flake8 -- run flake8
lint -- run pycodestyle and flake8
dist -- run python setup.py sdist
deb -- build a .deb package
rc -- buil resources
