Groovy resources that I find useful
The greatest thing about PHP, possibly its only advantage relative to other languages, is how well organized the website www.php.net is. If you want to look up the date() function, you can just type http://www.php.net/date and you will be taken to the page about the date function. That trick works for all functions.
With Groovy, information is less centralized. Partly that is because Groovy overlaps with Java, and so one has to look sometimes look up Groovy information, and other times look up Java information. But also, the Groovy modules all have homes, often at their own websites.
I will keep this page as a list of links I’ve found useful.
