# There are 3 configuration files :
# 1) "./autoconfig.h" is auto-generated and used only internally during build
#    (usually named "config.h" but conflicts with the file below)
# 2) "./upnp/src/inc/config.h" is static and contains some compile-time 
#    parameters. This file was previously in "./upnp/inc" but is no longer 
#    installed (contains internal definitions only).
# 3) "./upnp/inc/upnpconfig.h" is auto-generated and installed with the 
#    libraries : it contains information on the configuration of the
#    installed libraries.
