New Features of Eli Version 4.1
Repeated boolean options are now a count of the number of times the option appears rather than a list of keys each of which have the value 1. This is a potential source of incompatibility with previous versions.
Previously it was possible to have an integer or string value that was either the next argument or was joined to the option string. I.e., the following were possible
-#23 -m foo
It is now possible to have an option where the value can be either the next argument or can be joined to the option string. This is indicated by the keyword "with".
MacroPackage "-m" with strings "Load this macro package"; NumCols "-C" with int "Use this many colours"; NumZaps "-z" with ints "Zap this many times";
It is now possible to have more than one option string that invokes a particular option. Just list more than one string.
MacroPackage "-m" "mac" with strings "Load this macro package"; NumZaps "-z" "-Zap" "whammo" ints "Zap this many times";
Empty .clp files are now acceptable. The resulting processor will accept standard input, but nothing on the command line.
