#Host script for TinyCore, automatic ~30 MB Core linux client setup to run an OpenNARS NarNode with custom input:

#get tinycore, openjdk-8 minimal opennars, if not already there:
ls Core-10.1.iso || wget http://www.tinycorelinux.net/10.x/x86/release/Core-10.1.iso
ls openjdk-8-jre-compact2.tcz || wget www.tinycorelinux.net/10.x/x86/tcz/openjdk-8-jre-compact2.tcz
ls intial_input.nal || echo -e "*volume=0\n<{nars} --> [good]>.\n<{?who} --> [good]>?" > initial_input.nal
ls opennars-3.0.3-SNAPSHOT.jar || wget 91.203.212.130/opennars-3.0.3-SNAPSHOT.jar

#copy over opennars

#create core.gz, replacing the old core.gz of standard TC:

#start the customized tinycore that will run OpenNARS on startup automatically using qemu with kvm support:
