MIME-type indices

Hi,

speaking of MIME types: One thing I would like to see in wwwoffle some
time is an index of lasttime / prevtime sorted by MIME types, as well
as by whether things are redirects.  (Sorting by file type is close in
that it allows me to skip tons of useless graphics files, but it is
not sufficient.)

The downside compared to other indices is that every file has to be
touched, which may be slow (but would not be a problem in my case).

Currently I am using a simple shell script to do some of that.  It
simply looks for given mime types in the first 1k of each file, but I
suppose that wwwoffle would know how to do this in a better way.

Regards,

Albert.
