title: Jekyll PDF URL *not* ending in ".pdf"
body: <p>I have a Jekyll blog hosted on GitHub Pages.  On the blog is my resume (resume.pdf).  The url to access this is something like "<a href="http://example.com/resume.pdf" rel="nofollow noreferrer">http://example.com/resume.pdf</a>"  .  Is there any way I can get rid of the file extension, ie. have the URL be "<a href="http://example.com/resume" rel="nofollow noreferrer">http://example.com/resume</a>" ?  I have scoured the Jekyll help pages to no avail.</p>
