+Latest change: Sun Mar 09 19:19:04 CET 2008 [mika]
+
+Notice:
+
+* requires xsel binary
+* requires python >= 2.4 (for urllib2), version 2.5 suggested :)
+* if python-notify is installed it's used as notification system
+
+History:
+
+* 2008-03-09: improve cmdline parsing logic [gregor herrmann]
+              include support for libnotify [mika]
+              usage information for -h/--help [mika]
+              provide output on stdout even when using xsel [mika]
+* 2008-02-11: initial version [mika]
+
+Whishlist:
+
+* support multiple keywords in one single invocation
+* use python-xlib instead of xsel,
+  like in http://kalvdans.no-ip.org/svn/saturnapps/selection.py ?
+* support something like a search gateway for anonymous search requests
+* support different backends (like fuzzy search in local dictionaries)
+* provide small selection menu for X, vim,...
