NOTE 05/21/2025:

This is a one person project and have very little sponsoring. I want to still maintain and develop sc-im, but I am the only income in my family and its becoming difficult to work as much as I would want.
If you can make a donation (see at the bottom), please do. Your help would be really appreciated!!
Thanks.
