+Compiling, optional dependencies and variables
+--------
+
+This SlackBuild script supports additional variables.
+
+1) Lua support
+
+Lua is an optional dependency. Pass LUA=yes to this script
+to enable Lua support.
+
+2) Custom Perl Compatible Regular Expressions
+
+Perl Compatible Regular Expressions version 2 without JIT
+support is enabled by default. You can change this by passing
+PCRE= to this script.
+
+Currently supported settings are listed in the Makefile.
+
+For example:
+ * Use PCRE=PCRE2_JIT to use libpcre2 with JIT support.
+ * Use PCRE=PCRE to use libpcre version 1.
+
+You can also use the variables as they're written in the
+Makefile, such as PCRE=USE_PCRE_JIT or PCRE=USE_PCRE=1.
+The script will parse them correctly.
+
+3) QUIC support (experimental)
+
+Starting with version 2.6.0, HAProxy supports HTTP/3 over QUIC.
+The QUIC support is currently experimental and requires QUICTLS.
+OpenSSL package shipped with Slackware 15.0 is not compatible
+with QUIC.
+
+Pass QUIC=yes to this script to enable HTTP/3 support.
+
+Check out these links for more information:
+* https://github.com/quictls/

+--------
+Logging
+--------
+
+If you want to enable logging, please first refer to HAProxy manual
+on how to enable logging and how to select which events to log.
+
+HAProxy log forwarding works fine with Slackware's sysklogd.
+
+There are example files located in /usr/doc/haproxy-*/examples
+The files are called syslog.example and logrotate.example.
+
+You might want to add something like this to your haproxy.cfg file:
+
+global
+   log /dev/log local0
+
+Note that rotating logs does not require restarting HAProxy.
+Instead, logrotate script should send a HUP signal to syslogger
+when rotating. Example script is included in syslog.example.
+Rotating has been tested with sysklogd (Slackware default) and
+syslog-ng.
+
+--------
+Automatic starting/stopping upon system start/shutdown
+--------
+
+To start HAProxy automatically when system is booted,
+add the following lines to /etc/rc.d/rc.local:
+
+   if [ -x /etc/rc.d/rc.haproxy ]; then
+       /etc/rc.d/rc.haproxy start
+   fi
+
+To stop HAProxy on system shutdown, add following lines
+to /etc/rc.d/rc.local_shutdown
+
+   if [ -x /etc/rc.d/rc.haproxy ]; then
+       /etc/rc.d/rc.haproxy stop
+   fi
+
+--------
+Privileges
+--------
+
+Like with the most rc scripts /etc/rc.d/rc.haproxy should be
+run as root. You can easily drop process privileges by specifying
+another user (and group) in the main configuration file.
+
+Add something like this to haproxy.cfg:
+
+global
+  user nobody
+  group nogroup
