Need to trim episode descriptions

[Jason Luka]

I typically post a javascript link to show a transcript after the episode description.  Is there a way I can tell RSS feed-builder to stop at a certain point?  Because at this point, it looks like this.

<description>The opening theme music for the upcoming drama “Smoke &amp; Mirrors.” Click here for transcript (Transcript would normally go here)</description>

You can try going to the general settings of WordPress, in the Reading section, and switching feeds to Summary instead of Full Text.
