This script is the start of a helper tool that scans a source code and outputs the most recent libcurl version it finds symbols for. Meaning that if there's no conditions in the code, that's the earliest libcurl version the scanned code requires. It is not added to the Makefile.am yet as it is still a bit crude, but I'm committing it to keep it and allow us to work on it.
