Description

Almost all Unix (POSIX?) command line utilities have a nice feature of recognizing cascading defaults. The system-level one is typically named /etc/<util>rc and the user-level one is typically picked from ~/.<util>rc

I propose that we introduce the same for all of the /usr/bin launcher scripts that we support in Bigtop. The proposed format of the rc files is that of POSIX-compatible sh(1) code snippet with an overall effect of exporting those variables that affect execution.

Thoughts?
