 I try to monitor the Grease Monkey Mail List.
 http://www.mozdev.org/mailman/listinfo/greasemonkey
 Please post questions/comments and suggestions.


 This is an experimental test to provide the automatic copy to clipboard 
 of highlighted text as found in most linux distributions.  It has been tested with FF-Windows

 If you do not specify the domain to be used (using the grease monkey menu Highlight-Copy Site)
 This script will be actie on every site.  Due to the security issues with this script.  It 
 Will prompt you before accessing the priviledged function calls.

 Until the script is signed - in order to use it, you need to change a config setting in about:config
 user_pref("signed.applets.codebase_principal_support", true);
 Please be aware of the security issues which go along with this change.

--------------------------------------------------------------------

 This is a Greasemonkey user script.

 To install, you need Greasemonkey: http://greasemonkey.mozdev.org/
 Then restart Firefox and revisit this script.
 Under Tools, there will be a new menu item to "Install User Script".
 Accept the default configuration and install.

 To uninstall, go to Tools/Manage User Scripts,
 select "XMLHttpRequest versioning", and click Uninstall.
