title: Grails: Get calling file's name in custom taglib code
body: <p>I'm writing a custom tag library and I was wondering if it's possible to get the filename of the file that invoked the custom tag?  I need that tag to behave differently depending on which file calls it and if I can get the name that would be the best approach.  Otherwise I'll just have to pass it parameters to tell it how to behave.</p>
