A dead simple script that installs (build) dependencies, clones Supercollider and sc3-plugins, builds it, and finally will install it.
Supercollider
3.10.3
sc3-plugins
3.10
$ git clone https://github.com/kshoji/build-supercollider/
$ cd build-supercollider
$ ./deploy_sc.sh
That's all. Keep in mind this script works on Debian-derivates distributions (such as Ubuntu, Mint, etc). Sorry Windows, OS X, and other GNU/linux distros.
See README-deb.md for thoughts on making .deb packages.
