>Description:
Tbb (Intel Threading Building Blocks) version of par2cmdline tool. This version is available on : http://chuchusoft.com/par2_tbb and is actively maintained.
Note : the files/ directory include a .h file coming from the tbb port itself. This file is necessary for compiling the tool and is *not* available in the local include directory.
>How-To-Repeat:
>Fix:
Patch attached with submission follows:
# This is a shell archive. Save it in a file, remove anything before
# this line, and then unpack it by entering "sh file". Note, it may
# create directories; files and directories will be owned by you and
# have default permissions.
