The following is a snipplet of code I am revamping at work..

---------------------
if($argv) { // this is to be able to start it from commandline
  start_stars($argv[1],$argv[2]);
}

### Set working dir?
function start_stars($lang){
---------------------

Problems
==
- The first comment is rather useless. It states the obvious without actually adding information.
- $argv is checked but the number of arguments is never checked
- It is not explained what the arguments should actually contain
- The comment prior to the initialisation of the function is confusing. Is it a comment to the original programmer? Is it a suggestion? Who knows.
- The function name start_stars does not explain what the function does. It could mean anything.
- The function in itself only accepts one argument, so the second one is dropped!
