	Usage: clojure [dep-opt*] [init-opt*] [main-opt] [arg*]
	       clj     [dep-opt*] [init-opt*] [main-opt] [arg*]

	The clojure script is a runner for Clojure. clj is a wrapper
	for interactive repl use. These scripts ultimately construct and
	invoke a command-line of the form:

	java [java-opt*] -cp classpath clojure.main [init-opt*] [main-opt] [arg*]

	The dep-opts are used to build the java-opts and classpath:
	 -Jopt          Pass opt through in java_opts, ex: -J-Xmx512m
	 -Oalias...     Concatenated jvm option aliases, ex: -O:mem
	 -Ralias...     Concatenated resolve-deps aliases, ex: -R:bench:1.9
	 -Calias...     Concatenated make-classpath aliases, ex: -C:dev
	 -Malias...     Concatenated main option aliases, ex: -M:test
	 -Aalias...     Concatenated aliases of any kind, ex: -A:dev:mem
	 -Sdeps EDN     Deps data to use as the last deps file to be merged
	 -Spath         Compute classpath and echo to stdout only
	 -Scp CP        Do NOT compute or cache classpath, use this one instead
	 -Srepro        Ignore the ~/.clojure/deps.edn config file
	 -Sforce        Force recomputation of the classpath (don't use the cache)
	 -Spom          Generate (or update existing) pom.xml with deps and paths
	 -Stree         Print dependency tree
	 -Sresolve-tags Resolve git coordinate tags to shas and update deps.edn
	 -Sverbose      Print important path info to console
	 -Sdescribe     Print environment and command parsing info as data

	init-opt:
	 -i, --init path     Load a file or resource
	 -e, --eval string   Eval exprs in string; print non-nil values
	 --report target     Report uncaught exception to "file" (default), "stderr", or "none",
	                     overrides System property clojure.main.report

	main-opt:
	 -m, --main ns-name  Call the -main function from namespace w/args
	 -r, --repl          Run a repl
	 path                Run a script from a file or resource
	 -                   Run a script from standard input
	 -h, -?, --help      Print this help message and exit

	For more info, see:
	 https://clojure.org/guides/deps_and_cli
	 https://clojure.org/reference/repl_and_main
