+libguf - typesafe C99 containers
+--------------------------------------------------------------------------------
+1. Intro
+----------
+"Look mom, no void pointers!"
+
+This is a work in progress of my personal header only datastructure and 
+algorithm utility library which (ab)uses the C pre-processor to achieve 
+typesafety. 
+
+There is no reason this exists apart from "this is kind of fun and silly",
+you should just use C++ :)
+
+It uses a similar approach of "include parametrisation" to achieve strongly 
+typed data structures as used in https://github.com/ludocode/pottery
+
+Look at "src/test/example.c" for an example. 
+
+
+2. How to build
+-----------------
+Setup CMake with 
+$ cmake -DCMAKE_BUILD_TYPE=Debug -S . -B build/debug
+
+And build the example with
+$ cmake --build build/debug/ --target libguf_example
+
+
+3. Tests
+----------
+The tests in src/test are written in C++20, which made it easy to just use the 
+STL types in order to check their behaviour against the custom libguf C types. 
+
+
+4. What it includes
+--------------------
+- guf_dbuf.h:	a dynamic array (like std::vector)
+- guf_dict.h: 	a hashtable (elements are stored contiguously, like python3's 
+                compact dicts)
+- guf_str.h: 	a string-buffer with short-string-optimisation (guf_str) and
+                a string-view (guf_str_view) type
+- guf_rand.h:   random number algorithms
+- guf_sort.h:   sort algorithms
+- guf_math.h:   math I guess?
+- guf_linalg.h: linear algebra types and algorithms for computer graphics etc.
+- ... and more
