Official TkDiff Version 5.3 is released

This latest release adds a single new feature (VPATH support), two reported issues (broken directory name-generation, and Perforce SCM support) along with the usual assortment of minor things like misspellings and Online Help clarifications. As always, we appreciate the assistance in identifying failing content - your willingness to report it simply makes it better for everyone. With regard to the "new" feature, it takes the form of a pseudo-SCM in that it is detectable by virtue of its environment-variable existence, and serves primarily as a means to locate a missing predecessor when too few files are requested for comparison.
In the online-help arena, there is now an explanation why there can be a need to carefully tune your preferred SCM preference setting if your runtime environment can detect more than the usual "one", as well as exposing the heretofore hidden internal precedence order of those SCM possibilities.
Please enjoy this latest version, and feel free to make suggestions should you encounter situations where additional capability might help.
