; You can give this script to ACL2 using something like:
;
; ACL2_CUSTOMIZATION=NONE acl2 < demo2-save.lsp
;
; This should create a demo2 script and Lisp image that:
;
; - Doesn't print any startup stuff
; - Doesn't read any customization files
; - Reads and processes the command-line arguments
;
; E.g.,
;
; $ ./demo2
; colorless green ideas sleep furiously
; $ echo $?
; 0
;
; $ ./demo2 --help
; demo2: how to write a command line program in ACL2
; -h,--help Print a help message and exit with status 0.
; -v,--version Print out a version message and exit with
; status 0.
; $ echo $?
; 0
;
; $ ./demo2 --version
; demo2: version 1.234
; $ echo $?
; 0
;
; $ ./demo2 --foo
; Unrecognized option --foo
; $ echo $?
; 1
;
; $ ./demo2 --help=17
; Option --help can't take an argument
; $ echo $?
; 1
