+# A gitignore for Altera Quartus II that tries to ignore almost all of the
+# automatically Quartus-generated files. This primarily leaves the project,
+# settings, source, and constraint files to be added. The files ignored do not
+# include the bulk of the MegaFunction Wizard generated files which enables
+# a cloned repository to be used (usually) immediately without regenerating
+# Altera IP blocks.
