- * - main(): the entry point for bfs(1), a breadth-first version of find(1)
- *     - main.c        (this file)
- *
- * - 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)
- *
- * - bfs_eval(): runs the expression on every file it sees
- *     - eval.[ch]     (the main evaluation functions)
- *     - exec.[ch]     (implements -exec[dir]/-ok[dir])
- *     - printf.[ch]   (implements -[f]printf)
- *
- * - bftw(): used by bfs_eval() to walk the directory tree(s)
- *     - bftw.[ch]     (an extended version of nftw(3))
- *
- * - Utilities:
- *     - bfs.h         (constants about bfs itself)
- *     - bar.[ch]      (a terminal status bar)
- *     - color.[ch]    (for pretty terminal colors)
- *     - darray.[ch]   (a dynamic array library)

- *     - mtab.[ch]     (parses the system's mount table)
- *     - pwcache.[ch]  (a cache for the user/group tables)
- *     - stat.[ch]     (wraps stat(), or statx() on Linux)
- *     - trie.[ch]     (a trie set/map implementation)
- *     - typo.[ch]     (fuzzy matching for typos)
- *     - util.[ch]     (everything else)
- *     - xregex.[ch]   (regular expression support)
