# Maintainer notes:
# - http_rewrite-independent pcre-support makes sense for matching locations without an actual rewrite
# - any http-module activates the main http-functionality and overrides USE=-http
# - keep the following 3 requirements in mind before adding external modules:
#   * alive upstream
#   * sane packaging
#   * builds cleanly
# - TODO: test the google-perftools module (included in vanilla tarball)

# prevent perl-module from adding automagic perl DEPENDs
