All routines are implemented purely in C (C23) as static functions in headers inside ./include/.
Tests use Google's GoogleTest 1.15.2 (included in ./tests/googletest/) and require a C++ compiler with C++20 support.
Tests for routines in the C headers are implemented in the C++ source files with the same name in the ./tests/ directory.
Media files (bronze.jpg, mobydick.txt, plato.txt, sqlite3.dll & synth.bin) used for testing are located in the ./media/ directory.
The text files are ebooks downloaded from Project Guttenberg.
