Description Csaba Henk 2011-03-18 13:04:02 UTC 
Adding "run" API for invoking external commands, with following features:

- arguments first collected, then the invocation happens with fork + exec
- flexible specification of arguments (besides si{mp,ng}le argument 
  addition, support for adding multiple of them at a time / specifying one with 
  printf style formatting) [ ==> goodbye printf percentage soup when composing  
  commands ]
- single point of error check
- simple command runs are done in just one line
- support for popen(cmd, "r") like functionality
