the following files: doc/filter-howto.txt doc/releases.txt aren't installed in /usr/share/doc I would be nice if they did since filter-howto.txt has crucial information regarding configuration. If you want I can send a patch to the ebuild. (tinyproxy-1.6.3) Thank you.
Beside the syntax of the filter file, there is nothing important in those files. I've added instead an info message in postinst, explaining what you need to know about filter option.
