• Name: UniConvertor
• Homepage: https://sk1project.net/modules.php?name=Products&product=uniconvertor
• Why we should include this into the repository? Inkscape needs it to open .cdr files.
• Is it open source? Yeah. You could download it from https://downloads.sk1project.net/uniconvertor/v1.1.5/uniconvertor-1.1.5.tar.gz

Note for Linux users: UniConvertor was refactored and some code portions were extracted in sk1libs package. So before UniConvertor installing you should install sk1libs (from https://downloads.sk1project.net/uniconvertor/v1.1.5/sk1libs-0.9.1.tar.gz). Another additional package is uniconvw (from https://downloads.sk1project.net/uniconvertor/v1.1.5/uniconvw-1.1.5.tar.gz). The package provides Gtk+ frontend for UniConvertor and therefore uniconvw installation is optional.
