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.
