wtf is altera-makefile?

Altera Quartus II Makefile is a tool for people who program FPGA chips (a type of reconfigurable hardware) using Altera's Quartus II software. Normally, Quartus forces you to use a graphical interface to manage and compile your projects. This tool lets you do all of that from the command line instead, which means you can build and program your hardware projects without ever opening the GUI. The tool is essentially a configuration file (a "Makefile") that automates the heavy lifting. You organize your work into a specific folder structure: your actual hardware description code goes in one folder, and the tool puts all the temporary files and junk that Quartus generates into a separate folder. To use it, you tell the configuration file where your code is, what your project is called, and which specific hardware chip you are targeting. Then, you just run a simple command, and the system handles creating and compiling the project. Another command sends the finished code to your physical FPGA board. This is designed for hardware engineers and hobbyists who prefer typing commands over clicking through menus. For example, if you are building a custom hardware device and want to integrate the build process into an automated pipeline, or if you simply find the Quartus graphical software slow and cluttered, this tool streamlines the workflow. It keeps your source code cleanly separated from the dozens of messy files that the compiler creates. The project makes a notable tradeoff in its simplicity. Because it relies on a straightforward folder structure and a single configuration file, it keeps things lightweight and easy to understand. However, it has a known limitation: if you use a specific Quartus feature called QSys to generate custom components, you have to manually place certain files in the right folder for the build to succeed. The README doesn't go into detail on a permanent fix for this, so users just need to be aware of that extra step.
