# This is the development version of haproxy with ssl, slz, pcre, jemalloc.
# Relies on FLX_USE_OPENSSL{,_STAT}, FLX_USE_PCRE{,_STAT}, FLX_USE_JEMALLOC{,_STAT},
# and FLX_USE_HAPROXY_STAT. Example :
#   FLX_USE_OPENSSL_STAT=1 FLX_USE_PCRE_STAT=1 FLX_USE_HAPROXY_STAT=1 FLXARCH=x86_64 pkg prepare
#   FLX_USE_OPENSSL_STAT=1 FLX_USE_PCRE_STAT=1 FLX_USE_HAPROXY_STAT=1 FLXARCH=x86_64 pkg compile

# Patches below 1000 are bugfixes and initial backports.
# Patches above 1000 are package-specific and late backports (eg: dlmalloc below).
