"""ArtProvider class that publishes images from modules generated by img2py.
Image modules must be generated with the -u and -n <name> parameters.
Typical usage::
>>> import wx, wx.lib.art.img2pyartprov, myimagemodule
>>> wx.ArtProvider.PushProvider(wx.lib.art.img2pyartprov.Img2PyArtProvider(myimagemodule))
If myimagemodule.catalog['MYIMAGE'] is defined, it can be accessed as::
>>> wx.ArtProvider.GetBitmap('wxART_MYIMAGE')
"""
