autosetup is a tool, similar to autoconf, to configure a build system for the appropriate environment, according to the system capabilities and the user configuration. autosetup is designed to be light-weight, fast, simple and flexible. Notable features include: * Easily check for headers, functions, types for C/C++ * Easily support user configuration options * Can generate files based on templates, such as Makefile.in => Makefile * Can generate header files based on checked features * Excellent support for cross compilation * Replacement for autoconf in many situations * Runs with either Tcl 8.5+, Jim Tcl or just a C compiler (using the included Jim Tcl source code!) * autosetup is intended to be distributed with projects - no version issues
