how to create a bookmark file with multiple javascript bookmarklets

I have created a bunch of javascript bookmarklets and would like to import them all en masse into Firefox. I considered creating a Netscape formatted bookmarks.htm file but all of my javascript bookmarklets are in multiple lines (Netscape bookmarks.htm file expects them in a single line with %20s and what not) and that appears to screw it up. Is there a way I can keep all my bookmarklets in a single file and import them into Firefox?
