Installing

mssh is a rubygem: gem install mssh. http://rubygems.org/gems/mssh

BUGS/TODO

• Optionally Incorporate stderr into -c, with $?
• allow commandline manipulation of ssh args
• factor out redundancy between bin/mssh and bin/mcmd (cli module?)
• incorporate range / foundation lookup syntax for -r
• json output mode
• to-file output mode
• lots of rough spots, not super slick yet
• needs testing real bad. 0.1 release
