Thanks. I send PR to palaver.
alecmocatta/palaver#15

[dalance]

I changed the dependency crate from palaver to process_path because almost all function in palaver were not used.
I released v0.8.6 and it can be cargo install.

Success! Thank you!

$ cargo install procs

   Installed package `procs v0.8.6` (executable `procs`)
