Tcl Library Source Code

In GNU C library, the getopt() or getopt_long() function modifies the order of argv to move all operands(options without dash prefix) to the end of argv.

So, for example,
"cp fileA fileB -p"
works well same as
"cp -p fileA fileB".
In cmdline package, this did not work.

By the way, GNU getopt() did not modify the contents of argv except for the order of elements.
It provides a variable "optind" as index pointing to the first operand in argv.

At the moment the title comes across as 'this is a bug' (due to the phrase 'not work correctly' in it).

The description on the other hand feels more like a feature request: 'make cmdline more similar to getopt'.

Please provide an example which demonstrates what Tcllib's cmdline did versus what you expected it to do.
