I'm stuck on how to create a data file that can be read and written to. If I used File::ShareDir, I find that I don't have permission to write to the data file (it's a json file with oauth info that has to be periodically udpated). If I stick the module in a directory within the module, the path to the data file cannot be found by both my test scripts and the module when it is actually installed . I suppose I could get the absolute location of the module on the system and tack that on the front of the file name but I'm wondering if there is a better recommendation for handling this problem. Thanks!
