-This repository contains the C++ implementation of the commandline flags module

README.txt

+A commandline flags library that allows for distributed flags.
+
+This package contains a library that 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.
+The devel package contains static and debug libraries and header files
+for developing applications that use the gflags package.

cmake/README_runtime.txt

+This package contains runtime libraries only which are required
+by applications that use these libraries for the commandline flags
+processing. If you want to develop such application, download
+and install the development package instead.
