0.9.5 - Custom Blocks update
+ now you can spawn custom blocks (from mods or plugins) using the commands specified in blocks.yml
for example:
- '/setblock %d %d %d IC2:blockOreCopper'
- '/setblock %d %d %d IC2:blockOreTin'
- '/setblock %d %d %d IC2:blockOreUran'
or
- '/setblock %d %d %d ic2:resource 4'

how to use:
you write the usual command to spawn any block where %d %d %d are the coordinates of x, y and z, respectively.
