- document object_id=$1 for manifest + gencode :-)

- update docs regarding flow in cdist-stages.text
- create man pages for new executables
- nuke legacy manpages

- prettify output of cdist-deploy-to, e.g.

Processing object __file/etc/cdist-configured
   transfering type explorers ...
   running type explorers ...
   running manifest ...
   running gencode ...
   transfering object to target ...
   running code ...
