    r37173 | fijal | 2007-01-23 11:26:32 +0100 (Tue, 23 Jan 2007) | 2 lines

    Adhere to --box option.

    ------------------------------------------------------------------------
    r37127 | fijal | 2007-01-22 13:48:33 +0100 (Mon, 22 Jan 2007) | 2 lines

    Add a few docstrings.

    ------------------------------------------------------------------------
    r37110 | hpk | 2007-01-22 00:39:24 +0100 (Mon, 22 Jan 2007) | 2 lines

    renaming some variables for more clarity

    ------------------------------------------------------------------------
    r37065 | arigo | 2007-01-20 17:15:10 +0100 (Sat, 20 Jan 2007) | 3 lines

    Choose a random free port when using the --runbrowser option,
    but stick to the fixed 8000 when using --startserver only.

    ------------------------------------------------------------------------
    r37063 | arigo | 2007-01-20 17:00:31 +0100 (Sat, 20 Jan 2007) | 5 lines

    webbrowser.open() may block until the browser finishes or not, so better
    start it from a background thread.  An case where it blocks is if you
    define the $BROWSER environment variable.


    ------------------------------------------------------------------------
    r37015 | fijal | 2007-01-19 17:24:32 +0100 (Fri, 19 Jan 2007) | 2 lines

    Major cleanup of hostmanage. Got rid of global functions in favor of some better-structured classes.

    ------------------------------------------------------------------------
    r36988 | fijal | 2007-01-19 13:25:05 +0100 (Fri, 19 Jan 2007) | 2 lines

    Improve the C-c support, also keep web interface informed about crashes/interrupts.

    ------------------------------------------------------------------------
    r36969 | fijal | 2007-01-18 20:10:36 +0100 (Thu, 18 Jan 2007) | 3 lines

    Move teardown hosts out of finally (needs further refactoring)
    Kill adddefaultoptions call for now.

    ------------------------------------------------------------------------
    r36964 | hpk | 2007-01-18 19:30:02 +0100 (Thu, 18 Jan 2007) | 8 lines

    move rconfig functionality to general Config object,
    with docstrings, and trying to change rsession accordingly.

    note that it's called "make_repr" and "merge_repr"
    the latter to make it obvious that we are changing
    the instance with the given repr.


    ------------------------------------------------------------------------
    r36962 | fijal | 2007-01-18 19:06:13 +0100 (Thu, 18 Jan 2007) | 3 lines

    Huge refactoring. Got rid of remote_options and session_options, two tests
    still fail, so it's intermediate checkin.

    ------------------------------------------------------------------------
    r36943 | fijal | 2007-01-18 16:09:30 +0100 (Thu, 18 Jan 2007) | 3 lines

    at least LSession should work now. Did not touched yet the remote options stuff,
    but some simplifications were done.

    ------------------------------------------------------------------------
    r36937 | fijal | 2007-01-18 14:22:54 +0100 (Thu, 18 Jan 2007) | 2 lines

    Create a branch for further config cleanups.
