 Kalico uses a C module to handle some kinematics calculations more quickly.

 Many distributions have a policy of compiling all python code before packaging

 ## Versioning
 
 If you are building a package of Kalico from git, it is usual practice not to
 ship a .git directory, so the versioning must be handled without git.  To do
 this, use the script shipped in `scripts/make_version.py` which should be run as
-follows: `python2 scripts/make_version.py YOURDISTRONAME > klippy/.version`.
