Diff3-OV is a rather simple perl-Tk script.
BS Editor: This project is a rather simple perl-Tk script which does the following:

-Walk over a given directory-tree, the so called base
-Compare the found source-code-files with the two versions derived from this base-version
show the gathered information as a graphical tree, with color-codes for the directories
-Colors used:
Green: no one changed any source-file in this directory
Yellow : we changed at least one file in this directory
Blue : The others changed at least one file in this directory
Orange : We as well as the others changed at least one file in this directory, but different files
Red : We as well as the others changed the same file(s) in this directory
-You can save the generated info as either PNG-Graphic-File or as DOT-File for further work
-As addition you also have the possibility to save the info as comma-seperated file (CSV) for input into e.g. a Spreadsheet
-On large source-trees the generated pictures will be rather big, so you have the possibility to bLend out:
unchanged directories
directories with changes only by us
directories with changes only by them you can free download Diff3-OV 0.32 now.
