# Hello, and welcome to makefile basics.
#
# You will learn why `make` is so great, and why, despite its "weird" syntax,
# it is actually a highly expressive, efficient, and powerful way to build
# programs.
#
# Once you're done here, go to
# http://www.gnu.org/software/make/manual/make.html
# to learn SOOOO much more.

Git ignore file for quartus II projects
View .gitignore
# Working with Altera Quartus II (Q2) and do proper versioning is not that easy
# but if you follow some rules it can be accomplished. :)
# This file should be placed into the main directory where the .qpf file is
# found. Generally Q2 throws all entities and so on in the main directory, but
# you can place all stuff also in separate folders. This approach is followed
# here. So when you create a new design create one or more folders where your
# entities will be located and put a .gitignore in there that overrides the
# ignores of this file, e.g. one single rule stating "!*" which allows now all
# type of files. When you add a MegaFunction or another entity to your design,
# simply add it to one of your private folders and Q2 will be happy and manage
