Bug#868498: xpdf: adding search command usable through xpdf's remote feature

[Stefan Petrea <stefan.petrea@gmail.com>]

Package: xpdf
Version: 3.04-1ubuntu1
Severity: wishlist
Tags: patch

Hi,

I've added a new feature that can be used to execute a search in a document
through the remote interface that xpdf provides. This was useful to me and is
a feature I've always wanted to see in xpdf.

Best regards,
Stefan
