+# amsmathutil25
+
+A bottom level c++ math and utility function library.
+
+My old math and utility library is both foundational to a lot that I've written since, and it is a *mess*. I've learned a lot since I started piling code into there in 2007. This is a major rewrite.
+
+I'll also include some threading support.
+
+Main items:
+amsarray - an array class
+     sorting, inserting, updating, deleting
+low-dimensional (2,3,4) vector and matrix datatypes
+complex numbers
+math operations
+
+Hopefully I can clean things up and make a *mostly* drop-in replacement for my current library.
