What problems does the sfeed project try to solve?

The sfeed program converts RSS/Atom feeds (XML) to a TAB-separated format.
There are additional formatting programs included in the repository to convert
this TAB-separated format to various other formats. There are also some
programs and scripts included to import and export OPML and to fetch, filter,
merge and order feed items.

* It uses a simpler text-based (storage) format: it stores entries per line as
  fields in a TAB-Separated-Value format. This format is simple to use with
  existing UNIX text tools.
* Network transparent: reads from stdin: this makes things like Gopher and Tor
  support really easy and flexible.
* Tools are separated into binaries each with their own purpose.
* Few dependencies: a C compiler and libc for the main program.
* Hand-written small non-validating XML parser, supporting the important parts
  of XML 1.0 and a subset of HTML. No support for crazy and insecure things like
  XML entity expansion (aka entity "bombs" aka "billion laugh" attack) or
  auto-loading of remote DTDs.
* Tested and works on many platforms and architectures.
* It has no bugs (prove me wrong by sending a patch) :P

I will demo some practical uses later on in this presentation.
