    Linux Desktop program to calculate results of competition home-match, based on layout of original paper form. Form default is the "old" 21 points / set, 2 winning sets. Teams are 3 players, and they play 9 games + one double game. Calculation of the individual winning sets (and lost), and winning matches (and lost) is done, like needed to fill the official form. Print function for empty or filled form and official form to send in. If you want to try the program, just download the kavvvka.gambas file and use the gambas2 interpreter. Created on openSUSE/KDE but should work on all main Linux distributions given that Gambas 2 is installed from the distro repositories (complete IDE = most easy, or interpreter and required libraries). Runs on very light hardware, like original Aspire1 with only 0.5 Gb mem and 8 Gb SSD, with openSUSE 11.4 (evergreen)!
