# Note to user:
#     If you must edit this file manually please stick to this style:
#         Use tabs, not spaces.
#         No tabs before definitons.
#         Seperate lines for curly braces.
#         Use 1 tab depth for start of code block in functions.
#         Function description is first comment in code block. 
#         Alias description is comment right side of alias definition.
#         
#     ...if you use a different style it may or may not
#        break the program and I can't help you.
