-# Experience has shown that the symbols-in-versions file is very useful to
-# applications that want to build with a wide range of libcurl versions.
-# It is however easy to get it wrong and the source gets a bit messy with all
-# the fixed numerical comparisons.
-#
-# The point of this script is to provide an easy-to-use macro for libcurl-
-# using applications to do preprocessor checks for specific libcurl defines,
-# and yet make the code clearly show what the macro is used for.
-#
-# Run this script and generate libcurl-symbols.h and then use that header in
-# a fashion similar to:
-#
-# #include "libcurl-symbols.h"
-#
-# #if LIBCURL_HAS(CURLOPT_MUTE)
-#   has mute
-# #else
-#   no mute
-# #endif
-#
