Automated placement of other ground tile materials would be nice when playing with other mods.

Added a variable for it and also added automatic tree removal.

I just replaced the file with this one... but it isn't placing the new material (skyblue concrete from Many Floors, mf-concrete-skyblue)

Maybe it doesn't work with .15?

edit: scratch all that. It doesn't work for me at all, whether or not I modify files. I'm running bob's and angel's.

The error message is:

error while running event concreep:on_tick(ID 0)

Concreep/control.lua:57: attempt to perform arithmetic on local 'radius' (a nil value)

A not well documented feature is roboports will copy the pattern of concrete under them if using colored-concrete or warning-concrete. It's trickier to support other flooring as I do not, for example, want to lay down bricks and rip up concrete in the process.
