anda_kip 0.13.1

//! Command-line syntax checker for `.kip` source files.
//!
//! The binary walks files or directories supplied on the command line, parses
//! every `.kip` file it finds with [`anda_kip::parse_kip`], and exits with a
//! non-zero status if any file is missing, unreadable, or syntactically invalid.
