AutoGen is a tool designed to simplify the creation and maintenance of programs that contain large amounts of repetitious text. It is especially valuable in programs that have several blocks of text that must be kept synchronized. libopts provides the runtime component of an autogen add-on that simplifies the maintainance of that portion of your code that parses command-line options. A common example where this would be useful is in creating and maintaining the code required for processing program options. Processing options requires multiple constructs to be maintained in parallel in different places in your program. Options maintenance needs to be done countless times. So, AutoGen comes with an add-on package named AutoOpts that simplifies the maintenance and documentation of program options. The msys-autogen package provides the autogen utilities and documentation. The associated msys-libopts package provides the runtime library and development files for AutoOpts, a semi- automated command line option parser library and toolset based on AutoGen.
