# These bits are passed to regex.set_syntax() to choose among

# are for literal searching.

# 0 means that a special characters (such as *, ^, and $) always have
# their special meaning regardless of the surrounding context.
# 1 means that special characters may act as normal characters in some

# $ - only special at the end, or before ) or |
# *, +, ? - only special when not after the beginning, (, or |
