"""finddiv - a grep-like tool that looks for division operators.
|
|
|
|
Usage: finddiv [-l] file_or_directory ...
|
|
|
|
For directory arguments, all files in the directory whose name ends in
|
|
.py are processed, and subdirectories are processed recursively.
|
|
|
|
This actually tokenizes the files to avoid false hits in comments or
|
|
strings literals.
|
|
|
|
By default, this prints all lines containing a / or /= operator, in
|
|
grep -n style. With the -l option specified, it prints the filename
|
|
of files that contain at least one / or /= operator.
