Let's use the file-system generic path separator here. File#pathSeparator

> Project: Apache Storm
> Issue Type: New Feature

> https://github.com/nathanmarz/storm/issues/32
> While trying to implement a multilang based bolt, I discovered that binaries
> outside of /usr/bin, /usr/sbin, and /sbin, are not found despite being
> installed in say, /usr/local/bin.
> Is there a way to specify a PATH variable so when storm creates the sub
> shell, these binaries can be located by name? If not, can we get one added?
> ----------
> nathanmarz: This is a good idea. For the meantime, does using the full path
> of the binary (e.g., /usr/local/bin/python) work around this issue?
> ----------
> dinedal: That works for processes that don't require any other environment
> variables.
> Also, in cases where developers have multiple versions of a program (say,
> RVM) and the production servers have another one installed on the system, it
> means changing code for deploying the topology.
> ----------
> nicoo: +1
> To work around this issue you can start your multilang bolt from a bash
> script that set all needed env vars.
