- * - main(): the entry point for bfs(1), a breadth-first version of find(1)

- *
- * - bfs_parse_cmdline(): parses the command line into an expression tree
- * - ctx.[ch] (struct bfs_ctx, the overall bfs context)
- * - expr.h (declares the expression tree nodes)
- * - parse.[ch] (the parser itself)
- * - opt.[ch] (the optimizer)
