-      This file contains all the file-operations for multicatcher.
-      20060404: 
-         found a undetected omission in open_file().
-         AFter lseek(), we should write a dummy byte so that
-         multicatcher.zzz has the right file size to start with.
-         Otherwise, it will grow as syncing progresses.
-
-	 Port the code to deal with Large_files.
-         esp in write_page(),
-         lseek(fout, (off_t)(page-1)*(off_t)PAGE_SIZE, SEEK_SET)
-      200603:
-         Remove the meta-data operation.
-         Each file's info (stat) is transfered to targets during
-         the OPEN_FILE_CMD. extract_file_info() in this file
-         is to get that stat info for the current entry(file).

-      Previously, memory mapped file was used for file IO
-      but later was changed to simple open() and lseek(), write().  
-      This was also echoed in a patch by Clint Byrum <clint@careercast.com>.
