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()
