# Find xmlrpc
#
# Find the native XMLRPC headers and libraries.
#
# ::
#
#   XMLRPC_INCLUDE_DIRS      - where to find xmlrpc.h, etc.
#   XMLRPC_LIBRARIES         - List of libraries when using xmlrpc.
#   XMLRPC_FOUND             - True if xmlrpc found.
#
# XMLRPC modules may be specified as components for this find module.
# Modules may be listed by running "xmlrpc-c-config".  Modules include:
#
# ::
#
#   c++            C++ wrapper code
#   libwww-client  libwww-based client
#   cgi-server     CGI-based server
#   abyss-server   ABYSS-based server

# Typical usage:
#
# ::
#
