jflags is a C++ library that implements commandline flags processing. It's a fork of gflags library, with the following improvements :

• Compatible with the gflags API (Well, at least for the most used ones ;-))
• Unix-like flag naming convention (e.g. mySuperFlagflag is parsed from command line as --my-super-flag)
• New API to define a short name for a flag (e.g. DEFINE_short_bool(mySuperFlag, 'm', ...) to use -m on command line)
• User friendly instead of gflags' developper friendly help message (no source file name, no type information, ...)
• New API to declare a flag with a category
• Oh... and also moved to C++11
