// To use this script, visit ] and follow the new links for 'import' or 'export'
// there. The exported watchlist can be copy/pasted into the edit box for import, and is also legal
// (but somewhat obfuscated) wikitext for use with ]. Doesn't work in
// Internet Explorer, does work in Firefox 1, I haven't checked other browsers.

// To install this script, the easiest way is to type {{subst:js|User:ais523/watchlistei.js}} at the

// Each line of an exported watchlist is in the form
// *]

// Note that this feature is now part of the software, making this script redundant.
