* Available options
*
* =====> (string) cache_dir :
* - Directory where to put the cache files
*
* =====> (boolean) file_locking :
* - Enable / disable file_locking
* - Can avoid cache corruption under bad circumstances but it doesn't work on multithread
* webservers and on NFS filesystems for example
*
* =====> (boolean) read_control :
* - Enable / disable read control
* - If enabled, a control key is embeded in cache file and this key is compared with the one
* calculated after the reading.
*
* =====> (string) read_control_type :
* - Type of read control (only if read control is enabled). Available values are :
* 'md5' for a md5 hash control (best but slowest)
* 'crc32' for a crc32 hash control (lightly less safe but faster, better choice)
* 'adler32' for an adler32 hash control (excellent choice too, faster than crc32)
* 'strlen' for a length only test (fastest)
*
* =====> (int) hashed_directory_level :
* - Hashed directory level
* - Set the hashed directory structure level. 0 means "no hashed directory
* structure", 1 means "one level of directory", 2 means "two levels"...
* This option can speed up the cache only when you have many thousands of
* cache file. Only specific benchs can help you to choose the perfect value
* for you. Maybe, 1 or 2 is a good start.
*
* =====> (int) hashed_directory_umask :
* - Umask for hashed directory structure
*
* =====> (string) file_name_prefix :
* - prefix for cache files
* - be really carefull with this option because a too generic value in a system cache dir
* (like /tmp) can cause disasters when cleaning the cache
*
* =====> (int) cache_file_umask :
* - Umask for cache files
*
* =====> (int) metatadatas_array_max_size :
* - max size for the metadatas array (don't change this value unless you
* know what you are doing)
