    You can split up the functionality and import other scripts from the
    autoload script as you like.  This way you can share code between plugins.
 
+Searching for the autoload script in all entries in 'runtimepath' can be a bit
+slow.  If the plugin knows where the script is located, quite often a relative
+path can be used.  This avoids the search and should be quite a bit faster.
+Another advantage is that the script name does not need to be unique.  An
+absolute path is also possible.  Examples: >
+	import autoload '../lib/implement.vim'
+	import autoload MyScriptsDir .. '/lib/implement.vim'
+
 For defining a mapping that uses the imported autoload script the special key
 |<ScriptCmd>| is useful.  It allows for a command in a mapping to use the
 script context of where the mapping was defined.
