+ELinks is an advanced and well-established feature-rich text mode web
+(HTTP/FTP/..) browser. ELinks can render both frames and tables, is highly
+customizable, and can be extended via Lua or Guile scripts. It is very portable
+and runs on a variety of platforms. It also uses SpiderMonkey javascript
+support.
 
-ELinks also supports the gopher protocol.
+There are a number of options that can be used to add support for other
+protocols etc. To enable or disable an option use the following method:
 
-Various support options added into this SlackBuild:
+MOUSE=no ./elinks.SlackBuild
 
-Guile, CGI, NNTP, HTML-highlight, finger, bittorrent, gopher,
-exmode, 88 colours, 256 colours, true colour.
+Several options can be combined together.
 
-If you experience problems with corrupt graphics etc. it may be worth
-experiementing with various $TERM variables, as well as look into the
-settings for terminal options. EG:
+OPTIONS
 
-TERM=rxvt-unicode elinks <URL>
+Category       Description                         Default Value
 
-To disable the X windows mouse use the flag NOMOUSE=1
-To disable the gpm mouse use the flag NOGPM=1
-or combine them:
+System:
 
-NOMOUSE=1 NOGPM=1 ./elinks.SlackBuild
+FASTMEM        Direct use of system alloc          no
