Your code when copy pasted gives an error:
`Makefile:15: *** missing separator (did you mean TAB instead of 8 spaces?). Stop.` which is because of the medium rendering bugs. So I did replace all multiple spaces with a single tab.
After this, there is still an error:
kill: usage: kill [-s sigspec | -n signum | -sigspec] pid | jobspec ... or kill -l [sigspec]
actually do nothing
named files must be .go files
make: *** [app] Error 1
Any help on how to resolve this ?
