DFC project is a dedicated file cache.

DFC is a descendant if DCS -- Directory Content Service, an experimental
service that provides data access through shared memory mechanism of SysV IPC.

Both DCS and DFC are sponsored and intensively used by Kevin M. Liang in a
very busy webserver enviroment.

DFC examines its config file for the list of directories, all regular files
in these dirs are loaded into shared memory areas. Programs that need these
files can access the areas by ftok(). Owner and group of the area are set
after the original file, and permissions are 0440.

Programs that access shared memory areas first must read sizeof( off_t )
bytes of the area to determine its full length:

0123...................
|-T-|-------L---------|

T = L + sizeof( T )

Requirements:

· You need to have IPC support compiled into your kernel.

What's New in This Release:

· Fixed permissions on pidfile
