@foo@ / templates / sub packages

1.) Does anyone have a definitive list of variable names the PEAR installer will replace via the @foo@ stuff? 2.) Where do people put template files? If you use @data_dir@ and expect your code to have that expanded how do you easily test without packaging and installing? 3.) Anyone know where sub packages are documented? 4.) If you know the PEAR installer inside and out and are looking for work contact me offlist (or if you're a Python/PHP coder and just think working at Digg would be fun). Thanks! --Joe
