indicatrix-cli 0.8.0

Headless command-line tool for Indicatrix faceting designs: info, solve, metrics, validate, optimize, retarget, sweep and export from scripts, with no window. Reads .isdd (and older .indicatrix), .asc, .gem and .gcs; uses the same solver, retarget gate and optimizer as the desktop editor.

//! The `indicatrix-cli` program: runs the command line given to it and exits with its code.
//!
//! Everything else is in the library (`indicatrix_cli`): this only collects the arguments,
//! names a newer release on standard error first (`indicatrix_cli::take_update_check`), prints
//! the text a command returned and turns its exit code into the process's.
