* fixed some bugs where "unknown" tokens were allowed on the command line (which should really only be used for ortertun). * if an unknown token is encountered, print a short error to stderr and quit with a nonzero exit status * if we don't find the right number of parameters to an option, print a short error to stderr and quit with a nonzero exit status * when --help is given, print the help message to stdout (not stderr) and quit with a zero exit status * added --showme:help option to the wrapper compilers * updated docs in opal/util/cmd_line.h * other small/miscellaneous CLI parsing bugs in various tools I won't bore you with what we did before. :-) Here's some examples of what the new behavior looks like: {{{ % ompi_info --bogus ompi_info: Error: unknown option "--bogus" Type 'ompi_info --help' for usage. % ompi_info --param bogus ompi_info: Error: option "--param" did not have enough parameters (2) Type 'ompi_info --help' for usage. % }}} This commit was SVN r26072.
