The package names don't need to change. Just the class names. The transition can be easy by using Greg's suggestion: ---- PEAR/Date.php ---- // New file to conform with naming conventions. class PEAR_Date { // Actual gets moved into here. } ----------------------- ---- Date.php ---- // Old file with empty stub class for backwards compatibility. require_once 'PEAR/Date.php'; class Date extends PEAR_Date { } ------------------ With this pattern, the old and new files and class names remain in tact. Thus, older PEAR packages and userland scripts are not forced to change anything. This enhancement can even be done inside a regular release of a package. --Dan -- T H E A N A L Y S I S A N D S O L U T I O N S C O M P A N Y data intensive web and database programming http://www.AnalysisAndSolutions.com/ 4015 7th Ave #4, Brooklyn NY 11232 v: 718-854-0335 f: 718-854-0409
