# Improved XML highlighter by: Brian Candler <B.Candler@pobox.com>

# Define no. sync lines
# You can say:
# -200     means 200 lines
# -        means always start parsing from beginning of file when we lose sync
#          if nothing is specified, the default is -50

-

# Define colors
#
# bold inverse blink dim underline
# white cyan magenta blue yellow green red black
# bg_white bg_cyan bg_magenta bg_blue bg_yellow bg_green bg_red bg_black

# The underlines are here right now just because I want to distinguish which
# bits have been coloured (say) CdataStart, CdataBody, CdataEnd. And that's
# because I think it may be useful to make that distinction for some people.
