+class BuildSystem(object):

+    '''An abstraction of an upstream build system.
+    
+    Some build systems are well known: autotools, for example.
+    Others are purely manual: there's a set of commands to run that
+    are specific for that project, and (almost) no other project uses them.
+    The Linux kernel would be an example of that.
+    
+    This class provides an abstraction for these, including a method
+    to autodetect well known build systems.
