tcbuilder - Bash-based Build System

tcbuilder (also known as 'bb') is a Bash-based build system that generates automated Makefiles from user-defined bash variables. The current version is 1.0.4, released with an irregular cadence. It is designed for projects that already use Bash and Make, offering a lightweight alternative to full-featured build systems. Key differentiators include its simple variable-based configuration, no external dependencies beyond Bash and Make, and the ability to handle multi-group builds with per-source flags. It requires Node.js >= 20 for the npm package but the core build generator is purely bash scripts.
