I'm sure there are some better utils floating around, but this one seems to
work well for me.

import string, sys, glob

def main():
    tabSize=8 # I start with 8. Starting with 4 will break some files.
    g=glob.glob(sys.argv[1])
    print g
    a=raw_input('Tabs will be replaced with %d spaces\n Are you sure
Y/N:'%tabSize)
    if not a in ['y','Y']:
        return
    for a in g:
        buf=open(a).read()
        buf=string.replace(buf,'\t',' '*tabSize)
        open(a,'w+').write(buf)

main()
