Bug 813860

Description of problem:

Following examples from http://rhq-project.org/display/JOPR2/Running+the+RHQ+CLI are incorrect.


1- chapter RHQ CLI Command Line Options (subchapter Examples)
rhq-cli -u rhqadmin -u rhqadmin -c "pretty.print(ResourceTypeManager.findResourceTypesByCriteria(new ResourceTypeCriteria()))" > resource_types.txt

there are two options '-u', one of them should be '-p'

2- chapter Script Arguments (Handling Script Arguments example): 
if (args.length > 2) {              <<-- '>' should be '<'
    throw "Not enough arguments!";
}

for (i in args) {
    println('args[' + i '] = ' + args[i]); <<-- missing '+'
}

3- chapter Script Arguments (echo_args.js example)

for (i in args) {
    println('args[' + i '] = ' + args[i]);  <<-- missing '+'
}

4- chapter Script Arguments (box above echo_args.js example)
rhqadmin@localhost:7080$ exec -f echo_args.js --args-style=named x=1, y=2 
remove comma between 'x=1' and 'x=2'
