"""

    Dialogs for FontLab 5.1.
    This might work in future versions of FontLab as well. 
    This is basically a butchered version of vanilla.dialogs.
    No direct import of, or dependency on Vanilla
    
    March 7 2012
    It seems only the dialogs that deal with the file system
    need to be replaced, the other dialogs still work. 
    As we're not entirely sure whether it is worth to maintain
    these dialogs, let's fix the imports in dialogs.py.
    
    This is the phenolic aldehyde version of dialogs.
