g_spawn & g_io_channel: part II

[Vladimir Djokic <vladeck sezampro yu>]

    Good day,
    Developers. I tried looking at the Anjuta source, I tried reading 
the docs, and tried some googleing around. But, when I tried to do it, I 
realized: I'm DUMB ^_^
    There's a code in attachment, if someone can give me a hint: all I 
want is to start a shell command and print out its stdout and stderr values.

    Thank You,
    Vladimir.
