https://svn.lrde.epita.fr/svn/lrde-tools/trunk This should ease the transition to PySyck 0.61 (which supports multiple YAML document in a single file/stream) for Mac OS X users. TC's generators should run fine with the programs installed by this script. BTW, If you know how to create Portfiles for the MacPorts, don't hesitate to propose one for PySyck and one (update) for Syck to the MacPorts maintainers. (I think I know understand why this project is called Syck...) Index: ChangeLog from Roland Levillain <roland@lrde.epita.fr> Add a script making installations of PySyck easier. * src/install-pysyck: New installer. * README: Mention install-pysyck.
