# Check for XML parser, supporting libxml 2.x and expat 1.95.x,
# or a bundled copy of expat.
# * Bundled expat if a directory name argument is passed
# -> expat dir must contain minimal expat sources, i.e.
# xmltok, xmlparse sub-directories. See sitecopy/cadaver for
# examples of how to do this.

# Usage:
# NEON_XML_PARSER()
