SUMMARY = "Guile is the GNU Ubiquitous Intelligent Language for Extensions"
DESCRIPTION = "Guile is the GNU Ubiquitous Intelligent Language for Extensions,\
 the official extension language for the GNU operating system.\
 Guile is a library designed to help programmers create flexible applications.\
 Using Guile in an application allows the application's functionality to be\
 extended by users or other programmers with plug-ins, modules, or scripts.\
 Guile provides what might be described as 'practical software freedom,'\
 making it possible for users to customize an application to meet their\
 needs without digging into the application's internals."
