# 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 requirements in mind before adding external modules:
#	* alive upstream
#	* sane packaging
#	* builds cleanly
#	* does not need a patch for nginx core
# - TODO: test the google-perftools module (included in vanilla tarball)

# prevent perl-module from adding automagic perl DEPENDs
