This is the module for accessing local files and directories. The module contans

    #ifndef WWWFILE_H
    #define WWWFILE_H

    #ifdef __cplusplus
    extern "C" {
    #endif

### System dependencies

The sysdep.h file includes system-specific include files and flags for I/O to network and disk. The only reason for this file is that the Internet world is more complicated than Posix and ANSI.

    #include "sysdep.h"

### Access the Local File System

The WWWFile interface provides a platform independent access scheme for local files. The local file access works exactly like any other access scheme, for example HTTP, in that the "file protocol" is independent of the underlying transport. This can be used to for example slide in a CVS transport layser underneath the file module without making any modifications to the file module itself. You can read more about the transport managament in the Transport Interface.

    #include "HTFile.h"

### Content Negotiation

When accessing the lccal file system, you can enable content negotiation as described in the HTTP specification. The content negotiation algorithm is based on file suffixes as defined by the Bind manager. When looking for a file you do not have to specify a suffix. Instead this module looks for all alternatives with the same main name. For example, looking for the file Overview can result in any of the files (or directories) Overview.txt, Overview.html, Overview.ps etc. The selection algorithm is based on the values of the preferences for language, media type, encoding, etc. - exactly like a server would do with the `accept` headers.

    #include "HTMulti.h"
