+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.
