Description
int 
readgzfile ( string filename [, int use_include_path] )
 
   Reads a file, decompresses it and writes it to standard output.
  
   readgzfile() can be used to read a file which is not in
   gzip format; in this case readgzfile() will directly 
   read from the file without decompression.
  
Return Values
 
   Returns the number of (uncompressed) bytes read from the file. If
   an error occurs, FALSE is returned and unless the function was
   called as @readgzfile, an error message is
   printed.
