Too bad library documentation has taken a nosedive for a lot of modern tools. I blame all those automagic documentation/packaging tools that take some 2 line string and your args for each function and turn it into a boilerplate documentation page. You truly learn nothing you wouldn't by just looking at the source code of the function for pages generated like this. The author spends no additional time adding potentially useful information. A far cry from what you get when you man bash for example, where they even teach you how to file a bug report.
