autosetup is a tool, similar to autoconf, to configure a build system for the appropriate environment, according to the system capabilities and the user-selected options.

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 mismatch issues autosetup is particularly targeted towards building C/C++ applications on Unix systems, however it can be extended for other environments as needed.
