 StrongSwan is an OpenSource IPsec implementation for Linux.
 
-This build enables the OpenSSL extension which is included in the
-default Slackware install so it will cause no issues.
+This SlackBuild enables configure options which are known to compile
+without issue on a stock Slackware 14.2 system. These options provide
+additional functionality and increase this packages ability to
+inter operate with various vendor implementations. Unwanted and/or
+unnecessary plugins can be disabled a run-time via the 'load' flag in
+/etc/strongswan.d/charon/*.conf files.
+
+The following configure options are enabled by default:
+
+    --enable-shared
+    --enable-silent-rules
+    --enable-openssl
+    --enable-unity
+    --enable-curl
+    --enable-sql
+    --enable-sqlite
+    --enable-cmd
+    --enable-af-alg
+    --enable-gcrypt
+    --enable-aesni
+    --enable-sha3
+    --enable-files
+    --enable-lookip
+    --enable-eap-mschapv2
+    --enable-eap-tls
+    --enable-eap-ttls
+    --enable-eap-radius
+    --enable-ext-auth
+    --enable-xauth-eap
+
+To disable the above options set the environment variable CONFIG_OPTS
+to the empty string when calling this SlackBuild.
+
+Example:
+env CONFIG_OPTS=" " sh ./strongswan.SlackBuild
+
+To override the defaults options set CONFIG_OPTS to your desired set
+of configure options.
+
+Example:
+env CONFIG_OPTS="--enable-openssl --enable-unity" sh ./strongswan.SlackBuild
+
+To add to the default options without overwriting them set the
+EXTRA_CONFIG_OPTS environment variable.
+
+Example:
+env EXTRA_CONFIG_OPTS="--enable-socket-dynamic --enable-dhcp"  sh ./strongswan.SlackBuild
+
+The list of available options and their descriptions are available here:
