# Created by: Adrian Chadd <adrian@FreeBSD.org>

# Tunables not (yet) configurable via 'make config':
# SQUID_{U,G}ID
#   Which user/group Squid should run as (default: squid/squid).
#   The user and group will be created if they do not already exist using
#   a uid:gid of 100:100.
#   NOTE: older versions of Squid defaulted to nobody/nogroup.
#   If you wish to run Squid as "nobody" (which is not recommended), please
#   define SQUID_UID=nobody and SQUID_GID=nogroup in your make environment
#   before you start the update or installation of this port.
#
# SQUID_LANGUAGES
#   A list of languages for which error page files should be installed
#   (default: all)
#
#   E.g. use `make SQUID_LANGUAGES="English French"' if you want to
#   install the files for these languages only.
#   Use `make -VSQUID_LANGUAGES' or scroll down to this variable's
#   definition to see which values are valid.
#
# SQUID_DEFAULT_LANG
#   If you define SQUID_LANGUAGES, select which language should be the default
#   one (this variable defaults to English). This setting can be overwritten
#   with squid.conf's error_directory directive.
#
# SQUID_CONFIGURE_ARGS
#   Additional configuration options.
#
#   To enable them, use e.g
#   `make SQUID_CONFIGURE_ARGS="--enable-dlmalloc --enable-truncate" install'
#
#   The list below may be incomplete, please see the configure script
#   in the Squid source distribution for the complete list of additional
#   options.
#   Note that you probably do not need to worry about these options in most
#   cases, they are included in case you want to experiment with them.
#
#    --enable-dlmalloc
#     Compile and use the malloc package from Doug Lea
#    --enable-gnuregex
#     Compile and use the supplied GNUregex routines instead of BSD regex
#     (not recommended).
#    --enable-xmalloc-statistics
#     Show malloc statistics in status page
#    --enable-cachemgr-hostname=some.hostname
#     Set an explicit hostname in cachemgr.cgi
#    --enable-truncate
#     Use truncate() rather than unlink()
#    --disable-unlinkd
#     Do not use "unlinkd"
#    --with-aufs-threads=N_THREADS
#     Tune the number of worker threads for the aufs object
#    --with-coss-membuf-size
#     COSS membuf size (default: 1048576 bytes)
#    --with-maxfd=N
#     Override the maximum number of filedescriptors. Useful if you
#     build as another user who is not privileged to use the amount
#     of filedescriptors the resulting binary is expected to support.
#    --enable-ntlm-fail-open
#     Enable NTLM fail open, where a helper that fails one of the
#     Authentication steps can allow Squid to still authenticate the user
#    --enable-x-accelerator-vary
#     Enable support for the X-Accelerator-Vary HTTP header. Can be used
#     to indicate variance within an accelerator setup. Typically used
#     together with other code that adds custom HTTP headers to the
#     requests.
#    --enable-forward-log
#     Enable experimental forward_log directive.
#    --enable-multicast-miss
#     Enable experimental multicast notification of cachemisses.
