[Efraim Flashner]

This looks good, I've been looking for more options for viewing test
from PDFs. A couple of comments inline in the patch:

This should be define-public, otherwise we won't be able to find the
package. Also, this looks like you can rename it to just pdftotext, the
python part of the name doesn't look necessary to me.

This shouldn't be propagated. If the output references poppler than a
regular input is fine. If it doesn't then the source should be patched
to use the package from the store.

This should be a full sentence.
