+    # match one of these forms. The actual regexp is at:
+    # http://mxr.mozilla.org/mozilla-central/source/toolkit/mozapps/extensions/internal/XPIProvider.jsm#130
+    # So the JID needs an @-suffix, and the only legal punctuation is
+    # "-._". So we start with a base64 encoding, and replace the
+    # punctuation (+/) with letters (AB), losing a few bits of integrity.

+    # (which is 108 chars long without the $JID).
+    # Then the unpacked XPI contains packaged resources like:
+    #  resources/$JID-api-utils-lib/main.js   (35 chars plus the $JID)
+    #
+    # We create a random 80 bit string, base64 encode that (with
