+Parchive 2.0 client by Yutaka Sawada
+
+/* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * */
+
+[ Note ]
+
+ This client support "Comments" in PAR files.
+ This supports Multi-Byte Character like Japanese.
+ This supports empty file (0 length file).
+ This supports sub-directory and empty folder (directory tree).
+
+ This verifies source files more speedy or closely by option.
+ This re-calculate inverting matrix when it was failded at certain parity block.
+ This search same source block as lost block in all Recovery-Set files and copy.
+ This does not use parity block when block size is 4-byte.
+ This trys to search available source blocks by their original order.
+ Thus this may recover with less parity block than other PAR 2.0 clients.
+
+ You may set many source files by file-list instead of command line.
+ Source files may locate different directory with Recovery files.
+
+ Max block size is 2 GB.
+ You cannot specify Non-Recovery-Set files. (Empty files are set.)
+ Number of source blocks is limited up to 32768. (Files are limited up to 65536.)
+ Number of creating recovery blocks is limited up to 65535.
+
+ This client consumes memory very much.
+ Verifying file use same memory as the file or double of block size.
+ Recovering block use more memory as the number of block is many.
+
+ This requires a PC of Windows Vista or later (Windows 7, 8, 10, 11).
+ This is developed with Visual Studio 2022 on Windows 10.
