実は、私の作成しているキャラクターのリグのファイルでは、Armatureの複製の処理でなぜかエラーが起こるので、このスクリプトの作者の方がBrender Artist Forumに投稿された古いバージョンとかを参考にして、スクリプトを改造したものを使っていました。
久しぶりにオリジナルのスクリプトを動かしてみたので、いろいろ混乱してしまいました。
何度もコメントをしてしまい、すみません。

# prior to running script, make a duplicate of a reference (constrained) armature and remove constraints from the clone.
# simplistic example where ref and clone have to be identical with respect to bone names and order
# select the unconstrained armature clone, then shift-select the reference armature object.
# the actual motion of the reference armature's bones will be keyed in the clone's pose ipo
