MultiPar was prized in the final vote of 2012's popularity contest over Vector

  There was a popularity contest over Vector, which selects the best and prize for each section from weekly/monthly ranking top 100 softwares in 2012. MultiPar was selected in System & Hardware section. I appreciate many users' help, and proud that my development is supported. I will try to improve MultiPar to become more major and common tool.

MultiPar on GitHub I made a GitHub web-page for MultiPar.
PAR3 Project I'm making sample implementation of PAR3 for Windows OS.
Updated par2cmdline The latest version of par2cmdline is available for Linux/Unix/Windows users.
  Because I made my PAR2 client (par2j.exe) independently from par2cmdline project, the command-line syntax and printing are absolutely different from par2cmdline family. If you want to replace an old par2cmdline on Windows OS, you can download Windows binary from here.
ParPar High performance PAR2 create client for NodeJS
ParParGUI GUI front-end to ParPar, a PAR2 creation tool
par2cmdline-turbo par2cmdline ParPar: speed focused par2cmdline fork
  If you want faster PAR2 creation, you would better use ParPar tools instead of MultiPar. Though my PAR2 client uses some optimization methods in ParPar by getting help of the author, original ParPar will be faster mostly.
