Detailed Description

microlisp CLI: REPL, single-expression eval, and script runner.

Usage: microlisp Interactive REPL on stdin. microlisp FILE Run FILE as a script (one or more top-level forms); print the last form's result. microlisp - Run stdin as a script (non-interactive). microlisp -e EXPR Evaluate EXPR and print its result. microlisp –help | -h microlisp –version | -V

Exit codes (stable for shell scripting): 0 success 1 evaluation error (read syntax, type error, unbound variable, etc.) 2 I/O error reading the input or writing to stdout, or an unknown option / unknown subcommand on the command line
