+# binary tests
+
+this folder contains binary source (.bs) files, that can be converted to .bin
+files using the provided makefile. these files can contain comments, and are
+processed using `m4` and `xxd`.
+
+example syntax:
+```
+00 00 00 00 ; this is an example binary source file
+repeat(5,8f) ; 5 0x8f bytes
+repeat(hex(a),bb) ; 10 0xbb bytes
+repeat(0x40,00) ; 64 0x00 bytes
+; ^ 0x prefix works too
+ff ; single byte
+00000000 ; 32-bit number
+; ^ this is the comment character
+```
+
+if compilation hangs, you probably broke the syntax
