TypoFixer.py

#Prerequisite is to keep all your files; which you want to modify; under one directory
#Run the SpellChecker.py first to find out the typos from files and
#dump the corresponding suggestions in a text file

#Now you have to manually go through the text file created by SpellChecker script
#And select the suggestions that you want to take care of.
#For example if the mycsfiletypos.txt file can have below entries
#namespace : name space, names pace, namesake, nameplate, whitespace, nameless, 
#readonly : read only, readout, readopt, readably, readily, 
#Versoin : Version, Verso in, 
#alread : already, Alfred, lipread, allured, altered, 

#And if I want to fix only the versoin and alread typos, because the other 2 entries are valid,
#then you should fix the file to contain only below lines
#Versoin : Version
#alread : already
#if you find all the entries in typos.txt are invalid, remove all the entries and just keep the empty file.
#or delete the file
#Then this script PythonTypoFixer.py should be run on the same directory.
