This tool is primarily intended to be used in combination with version control software such as WinCvs or TortoiseCVS, which allow you to specify an external Diff application to view differences between revisions or to review changes to documents before commit. However, not all types of files can be sensibly compared using one and the same tool, e.g. it doesn't make a lot of sense to compare two revisions of an image file or a (binary) Word document using your default text differ. Furthermore, some Diff tools might require additional arguments to be passed on the commandline or they may expect the file names to be passed in a different order than provided by the version control tool.
ProxyDiff acts as a mediator between the version control software and the external diff application(s). Using a simple .ini-file it allows you to configure any number of diff tools and associate them with file types by extension. Optionally you can also specify how arguments should be passed. Yet another option is to define that the user should be able to choose between a specific Diff application and the default application.
