vQmod 2.6.1

Modifying OpenCart core files greatly reduces your ability to upgrade your store to later versions, and can affect other modules and extensions. vQmod provides a mechanism by which modules requiring OpenCart core modifications can be installed without damaging the integrity of your core system for upgrades. vQmod keeps a list of filenames and changes required, in the form of one XML file per extension. These changes are then created as the core files are used, and the resulting files are stored as cached copies which are executed instead of the original, core PHP or TPL file.
