# Licensed under the same condition as the xorg-server.
# This script updates the .spec file (based on .spec.in) and inject versioned ABI Symbols from the X-Server,
# stored in a template file xorg-server-provides. The content of this file is verified during build, as the
# same script runs then again, extracting ABI versions from the source to be built. This ensures we can't
# publish a package with wrong ABI Versions being provided as part of the RPM Metadata.
# Driver-, Input and extension-packages are supposed to use the provided macros to ensure correct Requires.

# extract ABI Versions... this function is copied from configure.ac
