Dubyline is a command-line debugger implemented using dubylib.
(dubyline - duby command-line debugger)
This is the primary tool for testing dubylib.
dubyline could be used as an utility to test dubylib features.
A new feature should be added as a new-command into the debugger. Alternatively an existing command could be extended.
It's very easy to prepare dubyline for a certain test, by passing commands to be executed in a file.
dubyline -cmd listofcmds.txt target.exe
This allows to automate the process of testing features.
