# THIS IS OLD CODE: SEE FIXEOLN FOR A BETTER SOLUTION.
# perform global search/replace for files in current 
# directory (only);  ex: python %X%\tools\todos.py *.*
# see the fixeoln*.py scripts for a better approach:
# this version only looks in one dir, and does a simple
# string replace--adds redundant \r's if run todos more
# than once!!; need binary open mode on dos, else reads
# auto drop \r from \r\n, and writes auto add \r to \n.
