## SECTION=system_libraries config GFLAGS tristate prompt "gflags" select LIBC_M select LIBC_PTHREAD select GCCLIBS_GCC_S select GCCLIBS_CXX help The gflags library implements commandline flags processing. As such it's a replacement for getopt(). It has increased flexibility, including built-in support for C++ types like string, and the ability to define flags in the source file in which they're used. See https://code.google.com/p/gflags/ for info about it.
