# Copy this file into your maya scripts directory, for example:
#     C:/Documents and Settings/user/My Documents/maya/scripts/ml_resetChannels.py
# 
# Run the tool in a python shell or shelf button by importing the module, 
# and then calling the primary function:
# 
#     import ml_resetChannels
#     ml_resetChannels.main()

# 
# Set the selected channels in the channel box to their default values. If no
# channels are selected, resets all keyable channels.

# 
# Select channels in the channel box, and run the command directly, as a hotkey
# or shelf button. Run command line to use the transformsOnly flag, in order to
# only reset transform attributes. The excludeChannels argument takes a list of
# channel names to exclude. The resetPuppetControl() command is a wrapper for
# resetting puppeteer controls by skipping certain settings attributes.
