# An example hook script to verify what is about to be committed.

# exit with non-zero status after issuing an appropriate message if

# it wants to stop the commit.

# To enable this hook, rename this file to "pre-commit".

Error: Attempt to add a non-ASCII file name.

This can cause problems if you want to work with people on other platforms.

To be portable it is advisable to rename the file.

If you know what you are doing you can disable this check using:

  git config hooks.allownonascii true

	exit 1

# If there are whitespace errors, print the offending file names and fail.
