# Converts pagespeed_libraries.conf from Apache-format to Nginx-format,
# supporting the canonicalize_javascript_libraries filter.
# Inspired by https://github.com/apache/incubator-pagespeed-ngx/issues/532
#
# Usage:
#   scripts/pagespeed_libraries_generator.sh > pagespeed_libraries.conf
#
# Then have nginx include that configuration file and enable the filter
# canonicalize_javascript_libraries.
