TMTOWTDI,

If i'm going to comment my code (which i only do for something which others will have to see and/or maintain) than i use the following setup which i have derived from my coding experiences:

##
# Function: get_input
# Receives: nothing
# Returns : user input regarding previous menu, Taint checked and chom
+ped.
# Notes   : none
##

The notes area will explain any code that isn't self-documenting before one gets to the code. The "receives" and "returns" sections detail what will be set up before and after the function runs (pre/post-conditions). However, due to my idiosyncracies, they are usually pragmatic pre/post-conditions, not solid theoretical ones. When the code is written well it's only four lines. When it's not i'll have huge sections describing what's going on, which is usually when i decide to re-write it :-)

Anyway, there's another $0.02 for your hat,
