# If your regexps don't work well under 2.0b1, you can switch
# to the old engine ("pre") down below.
#
# To help us fix any remaining bugs in the new engine, please
# report what went wrong. You can either use the following web

# or send a mail to SRE's author:

# Fredrik Lundh <effbot@telia.com>
#
# Make sure to include the pattern, the string SRE failed to
# match, and what result you expected.
