Author: rjek Date: Wed May 30 00:53:35 2007 New Revision: 3305 URL: http://svn.semichrome.net?rev=3D3305&view=3Drev Log: Add UNIX-specific fetch_filetype() support. Uses /etc/mime.types by defaul= t, but can build minimal mappings if it doesn't exist. New code allows fil= e:// directory listings to be generated, although these are not sorted unli= ke under RISC OS, as POSIX dirent() doesn't specify sorting.
