I'll be using the bzip2 and lzma converters in Yelp.  I'm not
sure about the magic converter.  I might just throw it away and
go off the file name.  The magic detection is not suitable for
general use, though I think it's OKish for Yelp.  Although this
Debian bug report concerns me:

lzma is detected by shared-mime-info (i.e GContentType), but only if it
has the right extension. Extending the database with magic info
shouldn't be that hard though.

Also, when putting together chains of streams when content may
or may not be encoded, I think it would be useful to have some
sort of NullConverter, i.e. a GConverter that doesn't change
anything.  Would anybody else find that useful?

I'm not sure why you'd need this, you just don't add a
GConverterInputStream in that case.

Anyway, since I was one of the people wanting this, I thought
I'd share my first experiences with it.  I'm curious what other
people would like to do about GConverters for other compression
schemes.  The code is simple enough that I don't really mind
keeping it in Yelp.  But if other people are doing this stuff,
maybe we should talk about how to share code.

Yeah, sharing things like this is good, but we don't want every app to
link to these libraries, and even gio plugins are not free (even when
not used) since we load them once to see what extension points they

A gmodule-level caching scheme is in order...  Pango and gimp can use them too...

Its not a lot of code either, nor is it very complicated, so maybe cut
and paste is not such a horrible idea.

Well, we know where that would lead :).
