* There are many contributed modules in D6 that rely on libraries module to manage external plugins
* Almost all of these modules make a call to libraries_get_path() with only one argument (the lib resource) and do not include the second argument requesting the path to be returned with the base path cosiderations. Eg: http://drupalcode.org/project/filedepot.git/blob/617ebc4a5c95fc751b3a379...
* It makes sense for the libraries module to have the default option of returning the lib path with the base path (and if the basepath needs to be exluded then the second argument can be supplied as FALSE)
I hope that you would agree that this choice of default will mean modules work in all kinds of setups. Please accept the patch if you do :-)
